Abstract
A method includes parallel or serial ionization of a gas mixture by activating at least two ionization devices operating using different ionization procedures, and/or by ionizing the gas mixture in a detector to which the gas mixture and ions and/or metastable particles of an ionization gas are fed. The method also includes detecting the ionized gas mixture in the detector for the mass spectrometric examination thereof. A mass spectrometer for mass spectrometric examination of gas mixtures includes an ionization unit for ionizing a gas mixture and a detector for detecting the ionized gas mixture.
