Abstract
L'invention porte sur un pré-concentrateur d'analyte pour chromatographie en phase gazeuse, qui comprend généralement un tube pourvu d'un orifice d'évacuation restreint et conditionné avec un absorbant. Ce tube est utilisé comme contenant d'un injecteur chromatographique, comme piège d'adsorbant couplé à une colonne chromatographique et/ou comme piège d'adsorbant couplé à un injecteur d'échantillon. De préférence, un dispositif chauffant permet de chauffer le tube. Selon un mode d'exécution préféré, le pré-concentrateur d'analyte comprend également un accessoire isolant la colonne de façon à pouvoir isoler provisoirement la colonne chromatographique des substances s'écoulant dans le tube. .
