Beschreibung
Zusammenfassung:	A mass spectrometer which has an ion source for ionising a sample and a mass-analysing region for introducing the ions thus formed into a vacuum and analysing the ions by mass, the ion source being provided with an ion spray source which has a heated capillary which works at least under atmospheric pressure, the mid-axis of the capillary being directed along the middle of an opening, in order to draw off the ions, and the sharp end of the capillary, which is positioned in the vicinity of the opening, ionises a sample of a liquid chromatograph both in atmospheric-pressure ionisation mode and in thermospray-ionisation mode and analyses the masses of the ions, by means of which more exact analytical data of the sample is obtained.
