Although real-life gas chromatography analysis is a complex process depending on numerous factors such as molecular volume, chemical and physical properties, the form of the analyzed molecules, the temperature of the process, the adsorption abilities, other properties of the matrix, etc., the separation for many compounds depends on differences in boiling points.  2, record 1, English, - gas%20chromatographic%20analysis

A collective term including a large number of unit operations which, in one way or another, isolate the various components of mixtures. Chief among these are evaporation, distillation, drying, gas absorption, sedimentation, solvent extraction, pressure extraction, adsorption, and filtration. Specialized methods include centrifugation, electromagnetic separation(mass spectrograph), gaseous diffusion, and various types of chromatography.  2, record 2, English, - separation

A form of gas chromatography in which the moving phase is a gas and the stationary phase is a surface-active sorbent(charcoal, silica gel, or activated alumina). The separation is achieved by adsorption of the components of a sample.  4, record 3, English, - gas%2Dsolid%20chromatography

The physical states of the mobile and stationary phases give rise to four basic types of chromatography: gas-liquid chromatography (GLC), gas-solid chromatography (GSC), liquid - liquid chromatography (LLC), and liquid-solid chromatography (LSC). Of the four basic types of chromatography, the two gas systems are independent and not subject to subdivisions. Thus the terms "gas-liquid chromatography" and "gas-solid chromatography" adequately identify the techniques involved. The liquid systems are not as easily described and are not mutually exclusive, which can lead to considerable confusion.  5, record 3, English, - gas%2Dsolid%20chromatography

Dans cette définition, le premier mot spécifie la nature de la phase mobile et le second la phase stationnaire. En chromatographie gazeuse, la distinction entre gaz-solide peut paraître obscure : des liquides peuvent être employés pour modifier les phases stationnaires solides et les supports solides utilisés pour retenir les phases stationnaires liquides qui peuvent affecter le processus chromatographique. Dans un classement selon la nature des phases, le terme relatif à l'effet prédominent doit être choisi.  6, record 3, French, - chromatographie%20gaz%2Dsolide
