Alpha Function

Ion mobility spectrometry (IMS) is a technique used for the detection of chemical warfare agents (CWA), drugs, toxic industrial compounds (TIC), and explosives, when rapid detection should be performed (from a few to several seconds) for trace amounts of these substances. An important development of IMS technology is differential ion mobility spectrometry (DMS). DMS is also known as Field Asymmetric Waveform Ion Mobility Spectrometry (FAIMS). Detection possibilities of apparatus using the DMS method are based on the occurrence of the different mobilities of ions (K) in the alternating electric field. This dependence is characterized by the alpha function (α).This presentation shows methods and examples of the identification of chosen substances. The results for the dependence of coefficient α are specific for different types of substances. This specificity is used to identify vapours and gases.

Detecting Method

The technique of ion mobility spectrometry (IMS) offers a practical and fast detecting method in ambient conditions to estimate whether there may presence contrabands or even chemical warfare agents (CWAs). In this work we have investigated a self-made radioactive 63Ni (β emission) ionization source for ion mobility spectrometry employed with an atmospheric pressure to detect real CWAs, such as GB, GD, HD, VX from aerosol samples. Furthermore, we have experimentally studied the influence of drift tube temperature not only in ion cluster formation in the positive mode, but also the detection limitation of CWAs.
