Abstract

The ionization chamber (2) of the ion source of the mass spectrometer is constructed in normal manner, applying a sufficiently open geometry so that the chamber contamination caused by the sample might be reduced. This however entrains the drawback that comparatively large sample quantities are required because part of the sample is pumped out from the ionization chamber without being utilizable. The said conflict can be eliminated by applying the method of the invention, when the ion source is provided with a plurality of separate ionization chambers (2), of which whenever desired any one can be rapidly selected for use, without disturbing the vacuum or ion-optical conditions in the mass spectrometer. The method is particularly well applicable when employing a gas chromatograph as sample input unit (4) in analysis situations where the mass spectra of sample components succeeding each other rapidly are measured, or where it is desired to record low intensity mass peaks after the occurrence at the same mass numbers of very powerful mass peaks in the preceding sample component.
