What are the basic analysis methods for standard gases?

1： Gas chromatography

People who often conduct experiments should not be particularly unfamiliar with gas chromatography, as the vast majority of standard gas analysis can be completed through it. In the specific usage process, it is generally completed through relevant processing techniques such as direct counter concentration or reaction method to analyze gas volume. The range of analyzed content is relatively large, so its usage range in experiments is very wide, and it is basically used in laboratories. And this analysis method can effectively analyze the vast majority of gases such as hydrogen, oxygen, helium, carbon dioxide, etc.

2： Chemiluminescence method

The frequency of using chemiluminescence method in standard gas analysis is also relatively high, because its overall sensitivity is relatively high, and its selectivity performance is also good. Overall, it is simple and convenient to use, and the analysis speed is also relatively fast. And this method utilizes the luminescence phenomenon generated by certain chemical reactions to analyze the relevant gases, so it is widely used in the analysis of sulfides or safety standard gases, and the overall performance is also relatively good.

3： Non dispersive infrared analysis method

Many friends may not know much about this analytical method, but it is helpful for analyzing the content of components such as carbon monoxide, ethane, and methane in mixed gases. This method requires the use of professional non dispersive infrared gas analyzers, and the composition of this equipment is relatively complex. However, its effectiveness is relatively good, and it is also widely used in the analysis of standard gases, which is relatively common in many laboratories that require the use of mixed gases.

4： Micro oxygen analyzer

The use of trace oxygen analyzer in the analysis of standard gases is not particularly extensive, as it is generally more suitable for the analysis of high-purity gases. It can effectively determine the trace oxygen contained in high-level enlightenment, and related analysis is actually relatively difficult. The application of such devices has also been effectively completed in recent years with the continuous progress of related industry technology, but in many laboratories that require oxygen content, its usage rate is relatively high.

5： Other analysis methods

In addition to the above analysis methods, there are also some relatively traditional standard gas analysis methods in the laboratory, but their efficiency is not particularly high. When the gas volume is relatively large, they may not be particularly suitable, but if the gas volume is small, it can also be tried.

The basic analysis methods for standard gas are as follows. If you are relatively interested in these contents, you can actually learn more about them through various channels. And many devices are very common in laboratories, and friends who often do experiments have better channels. Wuhan ISOTOPE Technology Co., Ltd. Service hotline: 19526388246
