Thermal conductivity of gas


The thermal conductivity gas analyzer is an instrument for analyzing the gas composition by measuring the thermal conductivity of mixed gases according to the different thermal conductivity of various substances. It is well known that there are three basic ways of heat transfer, namely heat convection, heat radiation and heat conduction. In the heat conduction gas analyzer, the heat exchange formed by the heat conduction is fully utilized, and the heat loss caused by the heat convection and the heat radiation is suppressed as much as possible.


The thermal conductivity indicates the thermal conductivity of the material, and the relationship between the thermal conductivity of the material can be described by Fourier law. As shown in Figure 6-1, there is temperature difference in a substance, and the setting temperature gradually decreases along the ox direction. Take two points a and b in the direction of ox, the spacing is △x. Ta and Tb are the absolute temperatures of two points a and b respectively. The change rate of temperature along the direction of ox is called the temperature gradient of a point along the direction of ox. A small area △s is taken between a and b in the vertical direction of ox. Through the experiment, it can be seen that in the time △t, the heat transfer from a point at high temperature through a small area △s is proportional to the time △t and the temperature gradient △T/△x, and it is also related to the nature of the substance. The equation is:



The formula (6-1) represents the relation between the heat transfer and the relevant parameters, which is called the Fourier law. The negative sign in the formula indicates the heat transfer to the direction of temperature decrease, the proportional coefficient λ is called the thermal conductivity of heat transfer medium (also called thermal conductivity).
Thermal conductivity is one of the important physical properties of matter, which characterizes the ability of matter to conduct heat. The thermal conductivity of different materials is also different, and varies with the composition, pressure, density, temperature and humidity.
In the formula (6-1) can obtain:

Thermal conductivity of mixed gas


All the components except the components to be measured in the mixed gas are called background gas, and the components which have influence on the analysis in the background gas are called interference components.
The volume fraction of each component in the mixed gas is C1, C2, C3,…、Cn..thermal conductivity is λ1, λ2, λ3,…、λn The content and thermal conductivity of the component to be measured are C1 and λ1. The following two conditions must be met to measure with a thermal conductivity analyzer.
①  
The thermal conductivity of each component of the background gas must be approximately equal or very close. As: 
λ2≈λ3≈λ4…≈λn
②The thermal conductivity of the component to be measured is obviously different from that of the background gas, and the larger the difference, the better the thermal conductivity.
λ1》λ2 or λ1《λ2
When the above two conditions are satisfied:



 λ in formula——thermal conductivity of mixed gas


Thermal conductivity of the i component in a mixed gas


Ci——Volume fraction of the i component in the mixed gas


The formula (6-5) shows that the content of the component C1 can be obtained by measuring the thermal conductivity λ of the mixed gas.






Composition and working principle of instrument


The composition of the heat-conducting gas analyzer can be divided into two parts: the heat-conducting detector and the circuit. The thermal conductivity detector (commonly called transmitter) is composed of a thermal conductivity cell and a measurement bridge, the thermal conductivity cell as the bridge arm of the measurement bridge is connected in the bridge, so the two are inseparable. The circuit part includes voltage stabilizing power supply, constant temperature controller, signal amplifying circuit, linearization circuit and output circuit.






Working principle of heat conduction cell


Because the thermal conductivity of the gas is very small, its variation is smaller, so it is difficult to measure accurately by direct method. The thermal conductivity change of the mixed gas is converted into the change of the resistance value of the thermal element by the indirect method, and the change of the resistance value is easy to be accurately measured.

Figure 6-2 is the working principle of the heat conducting cell, a resistance wire with larger resistivity and larger temperature coefficient is tensioned and suspended at the center of a cylindrical metal shell with good heat conducting performance, the two ends of the shell are provided with an inlet and an outlet of gas, the cylinder is filled with the gas to be measured, and the resistance wire is heated by a constant current.


Since the current passed through the resistance wire is constant, the heat generated in unit time on the resistance is also constant. When the sample gas to be tested passes through the cell at a slow speed, the heat on the resistance wire is transmitted to the cell wall by the gas in a heat conduction way. When the heat transfer rate of the gas is equal to the heating rate of the current on the resistance wire (this state is called thermal equilibrium), the temperature of the resistance wire will be stable at a certain value, this equilibrium temperature determines the resistance of the resistance wire. If the concentration of the component to be measured in the mixed gas changes, the thermal conductivity of the mixed gas changes, the thermal conductivity rate of the gas and the equilibrium temperature of the resistance wire will also change, eventually resulting in the resistance of the resistance wire corresponding change, thus realizing the conversion between the thermal conductivity of the gas and the resistance wire resistance value.


The relation between the resistance of the wire and the thermal conductivity of the gas mixture is given by the following formula (the derivation is omitted)

In the formula, the resistance of Rn, R0-hot wire at tn(°C)(the temperature of hot wire in thermal equilibrium) and at 0°C is obtained.
a——Resistance temperature coefficient of hot wire
tc——Temperature of the air cell wall of the thermal conductivity cell
I——Current flowing through the heating wire
λ——Thermal conductivity of mixed gas
K——Gage constant, which is a constant related to the structure of the thermal conduction cell
The formula (6-6) shows that Rn and λ are single-valued functions when K, tc, and I are constant.
The hot filament material uses a plurality of platinum wires (or platinum iridium wires), the platinum wires have strong corrosion resistance, large resistance temperature coefficient and high stability. The platinum wire can be exposed and directly contacted with the sample gas to improve the response speed of the analysis. However, the platinum wire is easy to be eroded and deteriorated in the reducing gas, which causes the change of resistance value and in some cases also plays the role of catalyst. For this reason, glass film is usually used to cover the surface of the platinum wire. The heat-sensitive element covered with glass film has the advantages of strong corrosion resistance (hydrogen in chlorine can be measured) and easy cleaning, but the existence of glass film delays the time of reaching thermal equilibrium between gas and platinum wire, so the dynamic characteristics of the element are slightly poor.
The material used for manufacturing the heat conducting tank body is copper. In order to prevent the corrosion of the gas, a layer of gold or nickel can be plated on the inner wall and the gas path of the heat conducting pool, and the stainless steel can also be used for manufacturing.


Structure formation of heat conduction cell


The structure of the heat conduction cell is straight-through, convection, diffusion, convection diffusion and so on, as shown in Figure 6-3


（1）Straight-through
The measuring chamber is parallel with the main gas path, and the gas of the main gas path is distributed to the measuring chamber. The structure has fast reaction speed and small hysteresis, but is easily affected by the fluctuation of gas flow rate.
（2）Convection
The measuring chamber is connected with the main gas path inlet in parallel, and a small part of the gas to be measured enters the measuring chamber (circulating pipe). The gas is heated in the circulating tube, which causes heat convection, and pushes the gas to return from the lower part of the circulating tube to the main gas path according to the arrow direction. The advantage is that the gas flow fluctuation has little effect on the measurement, but its reaction speed is slow and the lag is large.

（3）Diffusion
A measuring chamber is arranged at the upper part of the main gas path, and the gas to be measured enters the measuring chamber through diffusion action. The advantages of this structure are less affected by the fluctuation of gas flow rate, suitable for gases with lighter mass that are easy to diffuse, but have larger hysteresis for gases with smaller diffusion coefficient.
（4）Convection diffusion 
A branch pipe is added to form a flow separation on the basis of the diffusion type to reduce the lag. When the sample gas flows from the main gas path, a part of the gas enters the measuring chamber in a diffusion mode, and is heated by the resistance wire to form an ascending gas flow. Due to the restriction of the throttle hole, only a part of the airflow enters the branch pipe through the throttle hole, is cooled and moved downwards, and finally is discharged into the main air path. The power of the gas flow superheating guide tank has both convection and diffusion, so it is called convection diffusion. The structure can not generate the gas reverse flow phenomenon, but also avoid the gas accumulation in the diffusion chamber, thereby ensuring the sample gas to have a certain flow rate. The heat conduction cell is insensitive to the change of pressure and flow rate of sample gas, and the lag time is shorter than that of diffusion. Due to the advantages, the convection diffusion type heat conduction cell is widely applied.






Measuring bridge


From the introduction above, we can see that the function of the thermal conductivity cell is to change the concentration of the components in the mixed gas into the resistance of the resistance wire value change, the use of bridge to measure the resistance is very convenient, and the sensitivity and accuracy are relatively high, so the various types of thermal conductivity gas analyzer almost adopt the bridge as the measurement link.
In the measurement bridge, in order to reduce the current fluctuation of the bridge or the influence of the change of the external conditions, the measurement bridge arm and the reference bridge arm are usually arranged, the measurement arm is the thermal conductive cell of the sample gas flow, the reference arm is the thermal conductive cell of the package reference gas (or the through reference gas), and the two have identical structural dimensions. The reference arm is placed on the bridge arm adjacent to the measuring arm and acts as follows.
①The heat loss of the measuring arm through the flow and radiation is almost the same as that of the reference arm, and the two offset each other, the change of the resistance of the hot wire is mainly determined by the heat conduction, that is, the change of the gas heat conduction ability.
②When the temperature change of the thermal conduction cell arm is caused by the temperature change of the environment, the reference arm and the measuring arm change in the same direction, which is mutually offset and beneficial to weaken the influence of the temperature change on the measuring result.
③By changing the reference gas concentration, the lower limit concentration of the bridge detection is changed, which is convenient to change the measurement range of the instrument.
In the bridge structure and bridge arm configuration mode, there are several forms such as single-arm series-connected unbalanced bridge, single-arm parallel-connected unbalanced bridge and double-arm series-parallel unbalanced bridge. Figure 6-4 is the structure of the double-arm series-parallel type unbalanced bridge which is commonly used at present. It adopts two measuring heat conducting cell and two reference heat conducting cell. In the figure, Rm is the resistance of the measuring arm, Rs is the resistance of the reference arm. The two measuring arms and the two reference arms are arranged at intervals to form a double-arm series structure, and the sample gas flows through the two heat conducting pools in series in turn.
The output of the bridge in the initial state is:

The above formula is the relation between △Rm and △Uo, and is also the expression of the measurement sensitivity of this kind of bridge. Compared with the single-arm bridge with the same structure, the measurement sensitivity has doubled.

Figure 6-5 is a combined heat conduction cell used in a double-arm series-parallel type unbalanced bridge, two measuring heat conduction cells and two reference heat conduction cells, the leads of which are respectively connected into the four arms of the measuring bridge, and each heat conduction cell adopts a convection diffusion type structure.
The four heat conducting pools are made of a metal material with good heat conducting performance, so that the temperature of the measuring pool and the reference pool can be at the same temperature, and when the ambient temperature changes, the influence on the four pool walls is equal, thus reducing the measurement error. The temperature control device can be used to keep the temperature of the whole heat conduction pool constant in the situation of high measurement precision.


Advances in thermal conductivity detectors


The inner volume of the thermal conductivity cell is of the order of milliliter, and the lower limit of measurement is in the order of 100ppm. With the progress of sensor technology, the micro thermal conductivity detector has been used in the thermal conductivity gas analyzer and thermal conductivity gas chromatograph produced abroad, the volume of the thermal conductivity cell is micro-upgraded, the thermal element is also micro, thus greatly improving the sensitivity of the inspection, the lower limit of measurement can reach the order of 10ppm, even the order of 1ppm, as shown in Figure 6-6, this kind of thin film resistance is made on the silicon wafer by using ultra-micro technology lithography of very thin platinum wire, from the figure, we can see that the structure of the thermal conductivity cell is diffusion.




Whole machine circuit
The circuit of CI2000-RQD heat conduction type Hydrogen Analyzer has been introduced in many books and teaching materials. The CI2000-RQD heat conduction type hydrogen analyzer produced by Chang Ai Electronics Company is taken as an example to briefly introduce the whole circuit of heat conduction type gas analyzer.

Microprocessor and digital processing technology are used in the circuit of CI2000-RQD. The whole circuit is shown in Figure 6-7. The heat conduction pool structure in the figure belongs to convection diffusion type, the measuring bridge power supply uses current source circuit. The measurement signal of Wheatstone bridge is sent to an amplifier which can be controlled by software to be amplified and filtered by a Butterworth low-pass filter, then the A/D conversion is controlled by a microprocessor, then the converted data is processed by the software to be digitized, including filtering, linear processing, scale conversion, error calculation and compensation of the influence of temperature and pressure etc., and finally output the signal.

Applications


The thermal conductivity gas analyzer is an effective method for measuring one component in two mixed gases (with a very large difference in thermal conductivity). The invention is mainly used for measuring H2, and is also commonly used for measuring the content of CO2, SO2 and Ar, and has wide application range. Here are some typical applications:
Measurement of H2 Content in Syngas from Ammonia Plant
H2 purity measurement in hydrogenation plant
Measurement of CO2 content in furnace flue gas
Measurement of SO2 content in production process of sulfuric acid and phosphate fertilizer
Measurement of Ar content in air separation device
Measurement of O2 in pure H2 and H2 in pure O2 during the process of hydrogen production and oxygen electrolysis
Measurement of H2 in Cl2 in Chlorine Production Process
Measurement of H2 Content in Hydrocarbon Gas
Monitoring of H2 and CO2 Content in Hydrogen-cooled Generator Sets
Monitoring in pure gas production, such as He in N2, Ar in O2, etc.


Measurement error analysis


Thermal-conductive gas analyzer is a kind of analysis instrument with poor selectivity. Although various measures have been taken in the design and manufacture of the instrument, the operating conditions have been specified, and the influence of some interference factors has been suppressed or weakened to some extent, but the basic error of the analyzer is generally within ±2%. The main reason is the influence of background gas composition on the analysis results.
The thermal conductivity detector of industrial gas chromatograph and the detector of thermal conductivity gas analyzer are identical, but the measurement precision element is higher than the latter. The reason is that after the sample is separated by the chromatographic column, only the binary mixed gas of a single component and a carrier gas enters the thermal conductivity tank, but it is difficult to do this in the thermal conductivity gas analyzer. The background gas is often a mixture of multiple gases, which will have different degrees of influence on the thermal conductivity of the sample gas, when the composition of the background gas changes, the influence is greater.
The measurement error of the heat-conducting gas analyzer is composed of two parts: the basic error and the additional error. The basic error is determined by the measuring principle, the structure characteristic, the signal conversion accuracy of each link and the display instrument accuracy. That is, the error of the analyzer when it works under the specified conditions. The additional error is due to the adjustment of the instrument, improper use or the change of external conditions. The main factors of the additional error of the thermal-conductive gas analyzer are: the composition and accuracy of standard gas; interfering the presence of components, dust and droplets; the pressure, flow rate and temperature of sample gas; the changes in the current of the bridge.


Influence of composition and precision of standard gas


Thermal-conductive gas analyzer, like other analytical instruments, needs to be calibrated regularly with standard gas, but the difference is that thermal-conductive gas analyzer requires more standard gas. In principle, the composition and content of the background gas in the standard gas should be the same as that of the measured gas, which is difficult to achieve in fact, but the thermal conductivity of the background gas in the standard gas should be consistent with that of the measured gas, otherwise the calibration results should be corrected. In addition, to ensure the accuracy of standard gas, the error must not be more than half of the basic error of the instrument.






Effects in the presence of interfering components in the sample gas


The existence of interference components in the sample gas is an important factor for generating additional errors. For example, when the CO2 content in flue gas is analyzed by the thermal conductivity CO2 analyzer, the SO2 in flue gas is the interference component, and its thermal conductivity is 1/2 of the thermal conductivity of CO2. If the SO2 content in flue gas is 1%, the error of the analysis result will be nearly 2%. It is necessary to understand the interference components in the background gas and their influence on the measurement. Table 6-2 shows the influence of the interference components in the measured gas on the zero point of hydrogen content measurement.

Understanding Your Specific Gas Analysis Needs
When it comes to selecting a gas analyzer supplier, one of the most critical steps is understanding your specific gas analysis needs. Not only does the right gas analyzer play an essential role in ensuring safety and compliance, but it also significantly impacts the efficiency and effectiveness of your operations. Given the wide array of gases that can be analyzed and various application contexts—such as environmental monitoring, industrial processes, and research laboratories—it is vital to articulate your unique requirements before approaching potential suppliers.

**1. Defining the Application Context**

The application for which you need a gas analyzer can dictate the type and capabilities of the equipment required. Are you monitoring air quality in an urban setting, performing emissions testing, or checking for leaks in a manufacturing process? Each application has its own set of criteria. For instance, environmental monitoring instruments should be sensitive to trace gases and capable of long-term operation without recalibration, while industrial applications may prioritize durability and ease of maintenance.

Understanding the specific gases you will analyze is paramount. Different industries deal with various gas compositions. For instance, the oil and gas industry frequently analyzes hydrogen sulfide (H2S) and methane (CH4), whereas food and beverage sectors may focus on carbon dioxide (CO2) and oxygen (O2) levels for quality assurance. Clearly defining what gases need to be analyzed will help you identify suppliers that specialize in those specific analytes.

**2. Accuracy and Sensitivity Requirements**

Once you've established the gases of interest, evaluating the accuracy and sensitivity requirements is essential. Different applications demand different levels of precision. For example, regulatory compliance in fields like environmental monitoring often necessitates highly sensitive instruments with detection limits in the parts per million (ppm) range or even lower. Conversely, applications in less regulated environments may afford some leeway in sensitivity.

Consult with your team about acceptable levels of uncertainty and required validation procedures. This information will shape your conversations with potential gas analyzer suppliers, enabling you to communicate the essential specifications your equipment must meet.

**3. Environmental Conditions and Location of Use**

Gas analyzers are often deployed in various environmental conditions, which can affect their performance. Considerations such as temperature, humidity, and the presence of dust or corrosive chemicals need to be made. If your analysis occurs in a harsh industrial environment, a rugged instrument that can withstand physical stress and chemical exposure becomes essential. On the other hand, laboratory settings might allow for less robust yet more precise and sensitive equipment.

Moreover, if the analyzer will be used in an outdoor environment, factors like wind speed, sunlight exposure, and even wildlife interactions should be considered. Use cases like this need a supplier who understands the importance of environmental durability and has options available.

**4. Integration and Compatibility**

The selected gas analyzer should not only meet the basic functional requirements; it also needs to integrate seamlessly into your existing systems or workflows. Consider whether you need the analyzer to connect with other measurement devices or monitoring software. This compatibility often determines the level of operational efficiency and data integrity you can achieve.

Investigate the types of output data formats the supplier supports, ensuring they align with your data management systems. A good gas analyzer supplier will provide not only the hardware but also the necessary insights into software solutions that can help streamline data acquisition and analysis.

**5. Service and Support Considerations**

Even after rigorously defining your gas analysis needs, working with the right gas analyzer supplier involves considering the long-term support they will provide. Inquire about their technical support options, warranty coverage, and calibrations. Understanding the support infrastructure is critical, especially for complex instruments that may require specialized knowledge for maintenance and troubleshooting.

Moreover, consider asking prospective suppliers about their training programs for staff who will operate the equipment. Comprehensive training can significantly enhance the accuracy of your measurements and extend the life of your analyzer.

By taking these factors into account, you can make an informed decision when selecting a gas analyzer supplier that will cater specifically to your operational needs. This alignment is essential not only for the effectiveness of your measurement processes but also for achieving the highest standards of safety and compliance within your industry.

First and foremost, start by investigating the supplier’s credentials. This includes certifications, licenses, and accreditations specific to the gas analysis field. Reliable gas analyzer suppliers should possess relevant industry certifications from recognized bodies, which affirm their adherence to established quality standards. Organizations, such as ISO (International Organization for Standardization), often provide certifications that indicate the supplier has satisfied rigorous assessment criteria for quality management systems. Not only does an ISO certification serve as a testament to the supplier's commitment to delivering high-quality products, but it also indicates that they continually strive to improve their processes and offerings.

Beyond certifications, evaluating the supplier’s experience in the field is essential. Experience manifests itself in various forms—years in operation, the breadth of their product line, and the extent of their service offerings. A supplier that has been operational for many years generally suggests a level of stability and expertise in the market. Such longstanding suppliers are often familiar with industry challenges, technological advancements, and regulatory changes that can influence the quality and operation of gas analyzers.

Moreover, the range of products a supplier offers can also serve as an indicator of their expertise. A supplier that specializes in a wide array of gas analyzers for different applications can showcase their knowledge of the technology, demonstrating that they can cater to diverse requirements and challenges. Furthermore, they should provide transparent information regarding the specifications, capabilities, and limitations of their products, indicating their readiness to discuss technical aspects with potential clients.

It is also essential to inspect the supplier's experience in serving similar industries or applications. By reviewing their portfolio and case studies, you can gauge their track record in your specific field—be it pharmaceuticals, food and beverage, petrochemicals, or environmental monitoring. Suppliers that have successfully worked with organizations in your industry will likely have insights into the unique requirements and regulations you may face. Additionally, their familiarity with various installation and operational environments will allow them to provide tailored recommendations and support, facilitating the adoption of their gas analyzers into your existing processes.

Supplier support is another significant factor intertwined with their credentials and experience. A competent gas analyzer supplier should provide comprehensive post-sale services and support that can range from installation assistance, calibration, maintenance, and technical training to troubleshooting issues. Your supplier should have a dedicated technical team with enough experience to ensure that your gas analyzer operates optimally throughout its lifecycle. Understanding how they manage their customer relations, including responsiveness and adaptability to customer needs, can also provide insight into their overall credibility.

In today's connected world, researching online reviews, testimonials, and case studies from other clients can also enhance your evaluation process. A reputable gas analyzer supplier should have a history of satisfied customers who can attest to the efficiency and reliability of both their products and services. Engaging in conversations with existing customers or seeking referrals can provide valuable insights into their experiences, revealing not just the strengths of the supplier but also any potential shortcomings to be cautious of.

Finally, take into account the supplier's commitment to innovation. In the field of gas analysis, technology is advancing rapidly, and suppliers should be actively involved in research and development. A supplier that invests in continual upgrading of their product offerings showcases a commitment to providing the best technology available, which is critical for maintaining competitive edge and compliance with emerging regulatory standards.

By thoroughly evaluating the credentials and experience of your potential gas analyzer suppliers, you lay the groundwork for a partnership that is built on trust, reliability, and expertise.

Assessing Quality and Reliability of Analyzers
When selecting a gas analyzer supplier, a crucial aspect that cannot be overlooked is the quality and reliability of the analyzers they provide. The rising demands of environmental monitoring, industrial processes, and emissions regulations make it imperative for organizations to choose analyzers that deliver accurate and consistent results. Assessing the quality and reliability of gas analyzers should involve a comprehensive evaluation of several factors that influence their performance, longevity, and ultimately, the success of the applications for which they are intended.

**Understanding the Importance of Quality**

Quality in gas analyzers is paramount. An analyzer that provides inaccurate readings can lead to disastrous outcomes, including safety hazards, regulatory violation fines, and detrimental effects on equipment and operational efficiency. High-quality gas analyzers are typically built to rigorous standards, utilizing superior materials and advanced technology. When looking for a supplier, scrutinize the specifications of their offerings, including sensitivity, accuracy, and detection limits.

One key indicator of quality is the certification status of the analyzers. Look for products that meet international standards such as ISO 9001 or specific industry standards like those established by the Environmental Protection Agency (EPA). Certification indicates that the supplier has implemented quality management systems designed to ensure consistent performance and reliability.

**Evaluating Reliability**

Reliability is another cornerstone of selecting a gas analyzer supplier. This aspect refers to the analyzer's performance over time and its ability to deliver dependable results in various environments. A reliable analyzer should operate consistently under fluctuating conditions such as temperature, humidity, and pressure, which can substantially impact measurements.

To assess reliability, it is prudent to investigate the supplier's track record.
