Title (EN) DETECTING A LOW PRESSURE GAS FEEDING CONDITION IN AN ANALYSIS INSTRUMENT
(FR) DÉTECTION D'UN ÉTAT D'ALIMENTATION EN GAZ BASSE PRESSION DANS UN INSTRUMENT D'ANALYSE
Abstract:
(EN) This invention concerns a method and a gas chromatographic instrument in which a gas feeding low pressure condition monitored by controlling an electric parameter applied on a proportional solenoid valve placed along the gas line, and wherein an alarm to the operator is foreseen when said parameter reaches a pre-set value.
(FR) Cette invention porte sur un procédé et un instrument de chromatographie gazeuse dans lequel un état de basse pression d'alimentation en gaz est surveillé par commande d'un paramètre électrique appliqué sur une électrovanne proportionnelle placée le long de la conduite de gaz, une alarme à l'opérateur étant prévue lorsque ledit paramètre atteint une valeur préréglée.
