Embodiment Construction

[0061] In general, it should also be noted that Figures 1 to 4 And 6 to 12 show the structure and electrical wiring of the gas analysis device or its ion mobility spectrometer, and Figure 5 Connections for pressure lines and feeds of gases and other substances are shown for the same object. The gas analysis devices described always have electrical connections and Figure 5 The combination of connections shown in , however, this has not been reproduced in combination for greater clarity.

[0062] exist figure 1 The gas analysis device 1 shown in FIG. 1 has an ion mobility spectrometer 2 having, for example, a tubular or cylindrical housing 3 . The housing 3 is divided into an ionization source area 4, a reaction chamber 5, an ion gate 6, a drift chamber 7, and an ion detector 8, as in figure 1 Arranged one after the other in the previously mentioned order as shown in . An ion detector 8 , for example in the form of a cup or a metal plate, which can be configured as a Far...

Abstract

The invention relates to a gas analysis device (1), which at least has an ion mobility spectrometer (2), characterized in that the gas analysis device (1) has a reaction chamber (5) for the ion mobility spectrometer (2). An active energy feed device (50) is configured for manipulating the density of free reaction ions in the reaction chamber (5) by means of energy feed. The invention also relates to a method for gas analysis by means of a gas analysis device based on ion mobility spectrometry.

Description

technical field [0001] The invention relates to a gas analysis device according to claim 1 , which has at least one ion mobility spectrometer. The invention also relates to a method for gas analysis by means of a gas analysis device according to ion mobility spectrometry according to claim 8 . Background technique [0002] The present invention relates primarily to the field of gaseous substance analysis, wherein the term gaseous substance is to be understood in the broadest sense and in particular also includes any mixtures. Among these gaseous substances, the specific substances contained therein are to be detected qualitatively and / or quantitatively. Therefore, there is an urgent need for cost-effective, compact, fast and sensitive gas analysis devices for detecting the analysis of complex gas mixtures. In the field of safety technology, for example, portable measuring systems are used to continuously monitor the density of various harmful substances in the environment...
