How to detect the C content in recovered hydrogen
Thread Content
In our factory’s laboratory, we are generally able to test for P, B, and impurities. I’ve never seen how to determine the C content in recovered hydrogen; what kind of instrument can be used for this purpose?
You need to have meteorological analysis. Mass spectrometer.
Chromatographic analysis to detect CO, CO2, CH4, etc
Dizzy! What kind of exhaust gas recapture system is this? In the design of CDI, this element cannot be removed; therefore, there’s no need for testing!
There’s a filter; a filter is added after the recycling system
The filter isn’t as good as expected; we use a dry method
Using gas chromatography – are you involved in analysis? For gas chromatographic analysis in polysilicon production, it is necessary to determine N2, O2, and total carbon in H2; total C includes CO2 and CH4
