METHOD AND APPARATUS FOR IONIZING AND GAS DETECTION APPARATUS PROVIDED THEREWITH

摘要

The invention relates to an ionization method for ionizing gaseous or vaporous substances (22) to be investigated. In order to carry out a cost-effective radioactivity-free ionization, the invention proposes the following steps: guiding the substance (22) to be investigated to a solid body surface (34) and illuminating the solid body surface (34) for ionizing molecules of the substance to be investigated by photo-induced electron transfer. Furthermore proposed are an ionization apparatus (16) for carrying out the method and a detection apparatus provided therewith for gas detection by means of ion mobility spectrometry.
