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
27 May 2014This 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.

TT24-7
Markes International LtdThe TT24-7 continuous air/gas monitoring system incorporates two electrically-cooled traps which operate in tandem to ensure 100% data capture. The TT24-7 thermal desorption system is a robust, transportable thermal desorption unit, convenient for installation onsite or in mobile response vehicles as well as conventional laboratories. The TT24-7 interfaces to GC(MS) or process MS technology and incorporates two electrically-cooled traps which operate in tandem to ensure 100% sampling efficiency (no dead times).
