The first gas-solid chromatography was performed by the Austrian scientist, Erika Cremer in 1944 using solid stationary phases for the separation of acetylene hydrogenation products. One of her students, Fritz Prior, did his PhD on gas chromatography, presented its qualitative abilities in 1947 and they published the work in 1951.

Jan 10, 2020 · In gas-liquid chromatography, a stationary phase is liquid that is immobilized on the surface of a solid support by adsorption or by chemical bonding. Gas chromatographic separation occurs because of differences in the positions of adsorption equilibrium between the gaseous components of the sample and the stationary phases (Figure \(\PageIndex ...

The solid or coated support is packed into a tube, with the gas flowing through it. Separation depends on the relative partial pressures of the sample components above the stationary phase. Liquid chromatography uses similar packed tubular columns and usually a pump to force a liquid mobile phase through the column.

Jan 01, 1971 · (1) The SLP distribution on a solid support was studied for a number of chromatographic systems. (2) The contribution of adsorption at the stearic acid/chromosorb P interface was investigated. The temperature dependence of the retention volume near the SLP melting point was studied in order to estimate the contribution of the adsorption at the gas-SLP interface.Cited by: 8
