In a liquid chromatographic system, removing at least part of a volatile component from the liquid sample stream after separation in a column (56) by flowing it through a volatile component-removal device (50) including a porous wall (68) having a surface coating of a permeable polymer less than 10 µm thick. A liquid chromatographic system in which volatile component is removed prior to separation across the same type of membrane or across a membrane made of a copolymer of perfluoro-2, 2-dimethyl-1,3-dioxole.
Dans un système chromatographique liquide, au moins un composant volatile d'un flux d'échantillon liquide est éliminé, après sa séparation, grâce à son écoulement à travers un dispositif permettant l'élimination des composants volatiles comprenant une paroi poreuse présentant un revêtement de surface d'un polymère perméable inférieur à 10 ?m d'épaisseur. Un système chromatographique liquide est utilisé pour réaliser ledit procédé, ainsi qu'un système chromatographique liquide, dans lequel le composant volatile est éliminé avant sa séparation à travers le même type de membrane ou à travers une membrane comprenant un copolymère de perfluoro-2,2-diméthyl-1,3-dioxole.
