CA 2513011
The invention concerns an equipment comprising a chromatographic column (1) with final detector (5) and a mass spectrometer, wherein the temperature of an interface including an outlet tube (7) and a capillary tube adjusting the flow rate to the spectrometer (8) is adjusted by means of a flow rate or pressure leakage sensor informing a control module (12) which adjusts the temperature of the interface to equalize the flow rates in the tubes ( 6 and 7).
Dans un appareillage comprenant une colonne chromatographique (1) à détecteur final (5) et un spectromètre de masse , la température d'une interface comprenant un tube de sortie (7) et un tube capillaire réglant le débit vers le spectromètre (8) est réglé à l'aide d'un capteur de fuite de débit ou de pression renseignant un module de commande (12) qui ajuste la température de l'interface pour égaliser les débits dans les tubes (6 et 7).
