20130161509 | METHOD AND APPARATUS FOR DETECTING AND IDENTIFYING GASES BY MEANS OF ION MOBILITY SPECTROMETRY - The invention relates to a method for identifying gases, which are ionized and the drift times of the positive and negative product ions through drift spaces are measured and the measured drift times are evaluated, wherein for measuring the drift times the product ions are accelerated to drift velocities by a resulting electrical field. It is provided that the positive and negative product ions move synchronously and in parallel in the same direction. | 06-27-2013 |
20130153762 | METHOD AND APPARATUS FOR IONIZING GASES USING UV RADIATION AND ELECTRONS AND IDENTIFYING SAID GASES - The invention relates to a method for ionizing and identifying gases, wherein the gases to be identified are ionized in a reaction chamber and the product ions are measured, wherein the measurement of the product ions takes place via electrical fields acting on the product ions and the detection is performed with a detector for ions. It is provided that ionization takes place via UV radiation, and that simultaneously or sequentially ionization by electrons takes place. The invention further relates to a device for ionizing and identifying gases, which includes an ion source chamber having an ion source and an ion mobility spectrometer. For this purpose, a partition between the ion source chamber and the ion mobility spectrometer has a UV-transparent window and a window permeable for electrons, wherein UV radiation and electron radiation can be generated in the ion source chamber with the ion source. | 06-20-2013 |
