Title (EN) GAS CHROMATOGRAPH-MASS SPECTROMETER (GC/MS) SYSTEM FOR QUANTITATIVE ANALYSIS OF REACTIVE CHEMICAL COMPOUNDS
(FR) SYSTEME DE CHROMATOGRAPHE EN PHASE GAZEUSE-SPECTROMETRE DE MASSE POUR UNE ANALYSE QUANTITATIVE DE COMPOSES CHIMIQUES REACTIFS
Abstract:
(EN) Described is a new gas chromatograph-mass spectrometer (GC/MS) system and method for quantitative analysis of reactive chemical compounds. All components (38, 40, 44, 46) of such a GC/MS system external to the oven (14) of the gas chromatograph are programmably temperature controlled (36) to operate at a volatilization temperature specific to the compound(s) sought to be separated and measured.
(FR) Nouveau système de chromatographe en phase gazeuse-spectromètre de masse et procédé pour une analyse quantitative de composés chimiques réactifs. Tous les composants (38, 40, 44, 46) d'un tel système situés à l'extérieur du four (14) du chromatographe en phase gazeuse sont thermo-régulés (36) par programmation afin de faire marcher le système à une température de volatilisation spécifique au(x) composé(s) que l'on veut séparer et mesurer.
