How to test hydrogen purity
Thread Content
There is something wrong with our chromatography. Is there any other more accurate method for testing hydrogen?
What specifications of hydrogen are used for chromatography? When testing hydrogen, we not only consider accuracy, but also range requirements.
To test hydrogen purity, just use the explosion method. If you are measuring hydrogen purity, you need to choose the appropriate method and instrument based on the sample conditions and measurement range.
Instruments for measuring hydrogen, that is, two types: TCD detects hydrogen and chromatography detects impurities. Others are to use physical property analyzers to measure impurities.
To measure hydrogen purity, you need to choose an appropriate method based on the sample conditions and measurement range.
1# winer.LIU has a method for measuring impurities. If the purity of hydrogen is very high, it is recommended to measure the impurities and back-calculate the purity. Some of GOW-MAC's instruments are also tested by DID instruments used by domestic Aihua. Cut the high-component host material and measure the impurity components to determine the purity of hydrogen.
Thermal conductivity can be used when the content is higher (such as >30%) and the Austrian instrument can be used when the content is lower.
You can also use a hydrogen analyzer to measure hydrogen content. You can consult online. There are many manufacturers with such meters. There are portable ones, online ones, etc., some are explosion-proof and some are not.
