Abstract: The aim of the invention is to create a method and a device for detecting harmful substances while eliminating or minimizing the drawbacks of an ion mobility spectrometer (IMS). Said aim is achieved by a method in which the sample gas flow is mixed with a reference gas before reaching the detectors (2, 3, 4, 5, 6) and is directed to several detectors (3, 4, 5, 6) located next to the IMS (2), the obtained test signals regarding the ratio between the gas flow in the test gas path (8) prior to the metering process and the gas flow of the reference gas are used for calculating the original concentration of the harmful substances in the test gas, whereupon an alarm can be triggered by means of predefined and stored test values via a simple comparison of the signal amplitudes or a pattern recognition. The test system is cleaned and rinsed following the measurement phase by feeding the reference gas, if necessary also an additional cleansing gas. Such methods and test systems are used for identifying harmful substances in ambient air.

Abstract: An ion mobility spectrometer sysem includes two cells (1) and (2) driven by a driven unit (12) so that the cells operate at opposite polarities and are switched between different polarities either at regular intervals or in response to detection of a substance in one cell. Two reagents are supplied to both cells (1) and (2), one promoting detection of a substance in the positive mode and the other promoting detection of a substance in the negative mode so that there is no need to switch reagents when the polarity changes.

Abstract: 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.

Abstract: IMS apparatus has an inlet with a preconcentrator (9) opening into a reaction region (3, 103) where analyte molecules are ionized and passed via a shutter (11) to a drift region (2), (102) for collection and analysis. A pump (21) and filter (22, 23) arrangement supplies a flushing flow of clean gas to the housing (1), (101) in opposition to ion flow. A pressure pulser (8) connects with the housing (1, 101) and is momentarily switched to cause a short drop in pressure, in the housing to draw in a bolus of analyte sample from the preconcentrator (9). Just prior to admitting a bolus of sample, the pump (21) is turned off so that the flushing flow drops substantially to zero, thereby prolonging the time the analyte molecules spend in the reaction region (3).

Abstract: A detection system comprises a housing having a sample inlet and a gas outlet, and a preconcentrator. The preconcentrator can include a microelectromechanical system (MEMS) configured to accumulate or release a dopant at selected times, and can be located inside or outside the housing. The detection system can include an ion mobility spectrometer, a mass spectrometer, or a combination thereof. A method of analyzing a substance comprises supplying a sample gas or vapor comprising the substance, accumulating a dopant in a first presconcentrator, releasing the dopant at selected times from the preconcentrator to an area containing the sample, ionizing the substance to generate detectable species, separating the detectable species, and determining the detectable species by a detection unit. The system and method allow the rapid introduction and removal of dopant to facilitate fast and accurate identification of the sample.
