Gas Chromatographic Analysis Of Bubbles In Glass

Gas chromatography appears to be particularly suitable for the analysis of gas bubbles in glass. The paper describes the results obtained by the author in the use of a gas chromatography, which has a thermal conductivity cell as a detector, a column or tricresylphosphate on chromsorb W for the separation of CO2, H2S, SO2 and a molecular sieve of 0.5nm for o2, N2, CO. With this apparatus it is possible in one operation to separate and analyse the gases in a bubble in the order CO2,O2,N2,SO2,H2S,CO within 25min. The minimum dia. of the bubble that can be analysed by proposed method is about 0.5mm.
