Abstract
(DE)
Die Erfindung betrifft ein Verfahren zur Spurenanalytik von Sticksoffmonoxid in olefinreichen Gasen mittels einer Gaschromatographen(GC)-Säulenschaltung und eines Chemilumineszenzdetektors sowie eine Vorrichtung zur Durchführung des Verfahrens. Die GC-Säulenschaltung ist transportable in einem Gehäuse eingebaut und wird nicht temperiert. Als GC-Säulen werden gepackte oder mikrogepackte Säulen eingesetzt.
(EN)
The invention relates to a method for carrying out trace analysis of nitric oxide in olefin-rich gases by means of a gas chromatographic (GC) flow-switching system and a chemiluminescence detector. The invention also relates to a device for carrying out said method. The GC flow-switching system is installed in a portable housing and its temperature is not controlled. The GC columns used are packed or micropacked columns.
(FR)
La présente invention concerne un procédé d'analyse de traces de monoxyde d'azote dans des gaz riches en oléfines, au moyen d'un circuit de colonnes de chromatographie en phase gazeuse (GC) et d'un détecteur de chimiluminescence. L'invention a également pour objet un dispositif pour mettre en oeuvre le procédé. Le circuit de colonnes de GC peut être transporté dans un boîtier dans lequel il est monté, et n'est pas tempéré. En tant que colonnes de GC sont utilisées des colonnes condensées ou microcondensées.
