8. Sample preparation
Gas chromatography is mainly used in organic chemistry, as inorganic products are relatively non-volatile. However, some can be analyzed after being quantitatively transformed into volatile compounds. For example, uranium can be chromatographed in the form of its hexafluoride.
In organic chemistry, it is often necessary to prepare the sample to be introduced into the chromatograph so that it is in an easily injectable form, yet still representative of the product to be analyzed. Depending on the case, the methods described briefly below may be used.
8.1 Methods without chemical transformation
Dissolution: if the product to be analyzed is solid or not very volatile, it is useful to inject it in the form of a solution....

- - La chromatographie en phase gazeuse est une technique ancienne et éprouvée, d'où un très grand nombre d'ouvrages. La liste ci-dessous ne prétend pas être exhaustive mais privilégie les ouvrages traitant de l'instrumentation plutôt que des applications. Les plus anciens appartiennent souvent à des éditions épuisées et ne sont consultables...
