Setting Up A Gas Chromatograph For The Analysis Of Bubbles In Glass

Gas chromatography appears to be particularly suitable for the analysis of gas bubbles in glass. The paper describes the experience gained by the authors in the use of a chromatography which has a thermal conductivity cell in a wheatstone bridge network as a detector, a column of sebacate on chromosorb W for the separation of C02, SO2 and H2S and a column of 5 A molecular sieve for the other gases. With this apparatus it is possible to analyse bubbles of about 0.5mm in diameter.
