Solubility of some carrier gases in stationary liquid phases used in gas-liquid chromatography

A simple gas chromatographic technique for the determination of the solubil ity of gases in low-volatile liquids was proposed. The procedure is based o n the introduction of a certain volume of the liquid saturated with the gas at atmospheric pressure into a gas chromatograph. The solubility of carrie r gases (helium, hydrogen, nitrogen, methane, and carbon dioxide) in variou s stationary liquid phases (SLP), such as pentadecane, polydimethylsiloxane PMS-100, and polyethylene glycol PEG-600, was studied. The carder gases st udied can be arranged in the following series by solubility in SLP: He < H- 2 < N-2 < CH4 < CO2. This order coincides with the series reflecting change in the retention values in GLC for different carrier gases.
