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.

Abstract: The invention relates to an ionization device with an ionization space formed in a container, an inlet system for supplying a gas to be ionized to the ionization space, an electron source having at least one filament for supply of an electron beam to the ionization space, and an outlet system for letting the ionized gas out of the ionization space. Electron optics having at least two electrodes are disposed between the filament and the ionization space.

Abstract: The invention relates to a holding device for at least one filament, comprising: at least one filament receptacle for receiving the at least one filament. The holding device is designed for the detachable attachment, in particular clamping attachment, of the at least one filament receptacle to a container of an ionization device. The invention also relates to a mass spectrometer comprising: an ionization device having a container in which an ionization space for ionizing a gas is formed, at least one holding device which is designed for the detachable attachment, in particular clamping attachment, of the at least one filament receptacle to the container, and a vacuum housing to which the holding device, in particular a base body of the holding device, is detachably connected.
