Carbon molecular sieve is a new type of gas chromatography stationary phase that appeared in the 1970s. It has the advantages of high temperature resistance, corrosion resistance, high column efficiency, long column life, simple operation and good reproducibility. Since 1973, we have been conducting research on this and achieved good results. The results of the application of several carbon molecular sieves in gas analysis in metals are introduced as follows.
1. Apparatus and reagents Apparatus: gc-790 metal gas analyzer; chromatographic analysis conditions: the carrier gas is argon, and the argon flow rate is 20ml/min.
