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.

The potential for using the microwave-induced plasma (MIP) as an ionization source is further explored. This source operates at atmospheric pressure, minimizing pumping problems and, through power and gas-flow adjustment, offers the possibility of selecting from elemental spectra to fragmentation spectra resembling those from electron impact sources. The effect of microwave power, carrier gas-flow rate, and injector-prob e configuration in the production of fragment ions is demonstrated with the use of perfluorotributylamine and tetramethyltin. Initial potential for liquid-sample introduction to the MIP is accomplished by using a direct-injection nebulizer (DIN) at higher reproducibility levels than in earlier studies.
