Abstract: front page image
(EN)Apparatus for a mass spectrometer is disclosed comprising an ion source, a heater (230) for heating a gas flow (224) to the ion source, a temperature sensor for monitoring the temperature of the heater (230), and a control system (236). The control system (236) is arranged and adapted to determine a flow rate of the gas flow (224) by monitoring the power supplied to the heater (230) and the temperature of the heater (230).
(FR)L’invention porte sur un appareil, pour un spectromètre de masse, qui comporte une source d’ions, un dispositif chauffant (230) pour chauffer un écoulement de gaz (224) vers la source d’ions, un capteur de température pour surveiller la température du dispositif chauffant (230) et un système de commande (236). Le système de commande (236) est agencé et conçu pour déterminer un débit de l'écoulement de gaz (224) par surveillance de la puissance fournie au dispositif chauffant (230) et de la température du dispositif chauffant (230).
