1. When pure argon is used as the carrier gas to measure the impurity component in the argon gas, the problem that the main component argon peak can cover the impurity peak is avoided, gas autosampler vials and the oxygen component content can be determined at the same time, and the gas chromatograph does not need to be equipped with an oxygen analyzer.
2. The gas chromatograph uses two columns for impurity separation, and can measure six kinds of impurity components of hydrogen, oxygen, nitrogen, carbon monoxide, carbon dioxide and methane in high purity argon in one injection;
3. Compared with pure argon as carrier gas and helium as carrier gas, carrier gas is cheap, easy to obtain and convenient to use;
4, gas chromatograph ADD detection limit is low.gas autosampler vials
This is the end of the introduction of Gas chromatograph ADD features. I hope it can help you.
