Detecting and Quantifying Toxic Industrial Compounds (TICs) with Proton-Transfer-Reaction Mass Spectrometry (PTR-MS)
In the course of the FP7-SEC project "SPIRIT" (Safety and Protection of built Infrastructure to Resist Integral Threats) we focused our research with Proton-Transfer-Reaction Mass Spectrometry (PTR-MS) on C-agents, specifically Toxic Industrial Compounds (TICs). Most TICs are readily available and represent a considerable threat when used in terroristic attacks. We show the principal procedure of PTR-MS detection measurements on two chemicals, namely phosgene and chloroacetone. With studies of the former we want to point out principle differences between measurements on a quadrupole mass filter based and a Time-of-Flight-based PTR-MS instrument and point out the respective benefits and drawbacks. For the latter we present the results of a diluted headspace measurement and illustrate the connection with security standards in buildings.
