A simple gas chromatographic technique for the determination of the solubility of gases in low-volatile liquids was proposed.
The procedure is based on the introduction of a certain volume of the liquid saturated with the gas at atmospheric pressure
into a gas chromatograph. The solubility of carrier gases (helium, hydrogen, nitrogen, methane, and carbon dioxide) in various
stationary liquid phases (SLP), such as pentadecane, polydimethylsiloxane PMS-100, and polyethylene glycol PEG-600, was studied.
The carrier gases studied can be arranged in the following series by solubility in SLP: He<H
2<N
2<CH
4<CO
2. This order coincides with the series reflecting change in the retention values in GLC for different carrier gases.
Key words gases - solubility - gas-liquid chromatography - stationary liquid phases - carrier gas
