Using the TT24-7 with Twin Electrically-Cooled Focusing Traps for Continuous Monitoring of Trace Level Toxic Chemicals (e.g. Chemical Warfare Agents) in Air
28 May 2014
This application note describes an evaluation of TT24-7 performance for trace level agents, such as HD and free (underivitised) VX. Both off-line and near real-time operation is discussed. Linear FPD calibration curves ranging from 15 ng to 10 pg for VX and from 2 ng to 0.2 ng for HD are presented.
