ABSTRACT
We have discussed various technologies employed for detection of CWA and TIC vapors. Each of those technologies offers unique desirable as well as undesirable features. There is considerable room for improvement. Increasing detection reliability and reducing the frequency of false responses continue to be major challenges. The recent emphasis on TIC detection capability in addition to that of CWAs has also created substantial challenges for researchers and developers. Such requirements limit the number of technologies that can be effectively used.
