Please help me with my IMS setup

  1. Sep 24, 2010 #1
    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?
    using a DC corona discharge as an ion source

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