Abstract

The invention relates to a mass spectrometer for analysing a gas by mass spectrometry, comprising: a controllable inlet system for pulsed feeding of the gas to be analysed from a process region outside the mass spectrometer into an ionisation region, an ionisation device for ionising the gas to be analysed in the ionisation region, an ion transfer device for transferring the ionised gas from a ionisation region via an ion transfer region into an analysis region, and an analyser for detecting the ionised gas in the analysis region. The invention further relates to an associated method for mass spectrometrically analysing a gas.
