    Why is My IMS Setup Failing to Detect TNT with a DC Corona Discharge Ion Source?

    sorry,can not find the reasons,may be,something wrong in the drift tube,something in the tube quenching the ions?

    Why is My IMS Setup Failing to Detect TNT with a DC Corona Discharge Ion Source?

    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
