I have built an IMS setup to detect explorsives such as RDX,PETN,etc. the setup can have the RDX and PETN spectra even in a much low concentration,but when for TNT detection,it fails to have any spectra.I want to know why?

Try searching Google with "Ion mobility spectrometry, IMS, TNT" and check the journal articles that appear.
