Oil analysis involves three levels of laboratory activity: sample preparation and clean up, basic identification, and final comparison. ... Typical analyses include observation of solubility in organic solvents, ... [and] gas chromatography ...

Méthode de séparation dont les principes généraux sont les mêmes que ceux énoncés pour la chromatographie en général, c'est-à-dire fondés sur la migration différentielle des constituants du mélange à analyser au travers d'un substrat choisi. La particularité du procédé est d'opérer en totalité sur des produits volatilisés, ce qui implique de maintenir une température minimale convenable, mais sans qu'il y ait volatilisation du substrat, et de travailler en circuit étanche au gaz. 7, record 1, French, - chromatographie%20en%20phase%20gazeuse

La chromatographie en phase gazeuse est une méthode de séparation des composés gazeux ou susceptibles d'être vaporisés par chauffage sans décomposition. Elle permet ainsi l'analyse de mélanges éventuellement très complexes dont les constituants peuvent différer d'une façon considérable par leur nature et leur volatilité. La chromatographie en phase gazeuse appartient à l'ensemble des techniques chromatographiques dont la chromatographie en phase liquide à hautes performances et la chromatographie en couche mince sont d'autres exemples importants. 8, record 1, French, - chromatographie%20en%20phase%20gazeuse
