Title (EN) TRACE DETECTION DEVICE AND ANALYSIS METHOD THEREFOR
(FR) DISPOSITIF DE DÉTECTION DE TRACES ET SON PROCÉDÉ D'ANALYSE
(ZH) 痕量检测仪和用于痕量检测仪的分析方法
Abstract: front page image
(EN)A trace detection device comprises an analysis chamber that delimits an analysis area (21), wherein the analysis chamber has a case that has an inlet (22) for feeding a substance to be detected into the analysis chamber and an outlet (23) for discharging a sample-carrying gas from the analysis chamber. A control unit controls the trace detection device in such a manner as to keep a fluid communicating between the inlet and the analysis chamber and also between the outlet and the analysis chamber, allowing for continuous feeding and sampling during the pre-concentration state. An analysis method for the trace detecting device is also disclosed.
(FR)La présente invention concerne un dispositif de détection de traces comprenant un séparateur destiné à définir une zone de séparation (21), et le séparateur possède un boîtier. Le boîtier a une entrée (22) destinée à charger une substance à détecter à l'intérieur du séparateur et une sortie (23) destinée à décharger le gaz comprenant l'échantillon provenant du séparateur. Une unité de commande sert à commander le dispositif de détection des traces de sorte à garder une communication fluidique entre l'entrée et le séparateur et également entre la sortie et le séparateur et à charger et à échantillonner en continu pendant la phase de pré-concentration. L'invention concerne également un procédé d'analyse pour le dispositif de détection des traces.
