ガスクロマトグラフィー用の化合物前処理濃縮器

Document Type and Number:

Japanese Patent JP4231480

Kind Code:

B2

Abstract:

An analyte pre-concentrator for gas chromatography is disclosed generally comprising a tube packed with an adsorbent, wherein the tube may serve as the liner of a chromatographic injector, as an adsorbent trap coupled to a chromatographic column, and/or as an adsorbent trap coupled to a headspace sampler. Preferably, a heating device allows the tube to be heated. In a preferred embodiment, the analyte pre-concentrator further comprises a column isolating accessory so that a chromatographic column can be temporarily isolated from substances flowing through the tube.
