“…The Riken group (Wako, Japan) and the author have developed an elemental analytical system using an electron cyclotron resonance ion source MS to detect CWAs. Phosphorus ions, chloride ions, and hydrogen cyanide fragment ions can be monitored to selectively detect nerve gases, chloride-containing CWAs, and AC and CK, respectively (Kidera et al, 2011;Urabe et al, 2014).…”

“…We have previously evaluated the performance of commercially available on‐site detection equipment, including handheld gas detection tubes, ion mobility spectrometry (IMS) instruments, an arrayed surface acoustic wave sensor and a Raman spectrometer . Moreover, we have developed new field‐deployable detection equipment, such as an amperometric sensor, an atmospheric pressure counter‐flow chemical ionization ion trap mass spectrometry (MS) instrument, an electron cyclotron resonance ion source MS instrument and a low‐temperature plasma ionization MS instrument . Within field‐deployable technologies, gas chromatography (GC)–MS instruments are the most promising candidates .…”

A field-portable gas chromatography-mass spectrometry (GC-MS) system (Hapsite ER) was evaluated for the detection of nonvolatile V-type nerve agents (VX and Russian VX (RVX)) in the vapor phase. The Hapsite ER system consists of a Tri-Bed concentrator gas sampler, a nonpolar low thermal-mass capillary GC column and a hydrophobic membrane-interfaced electron ionization quadrupole mass spectrometer evacuated by a non-evaporative getter pump. The GC-MS system was attached to a VX-G fluoridating conversion tube containing silver nitrate and potassium fluoride. Sample vapors of VX and RVX were converted into O-ethyl methylphosphonofluoridate (EtGB) and O-isobutyl methylphosphonofluoridate (iBuGB), respectively. These fluoridated derivatives were detected within 10 min. No compounds were detected when the VX and RVX samples were analyzed without the conversion tube. A vapor sample of tabun (GA) was analyzed, in which GA and O-ethyl N,N-dimethylphosphoramidofluoridate were detected. The molar recovery percentages of EtGB and iBuGB from VX and RVX vapors varied from 0.3 to 17%, which was attributed to variations in the vaporization efficiency of the glass vapor container. The conversion efficiencies of the VX-G conversion tube for VX and RVX to their phosphonate derivatives were estimated to be 40%. VX and RVX vapors were detected at concentrations as low as 0.3 mg m . Gasoline vapor was found to interfere with the analyses of VX and RVX. In the presence of 160 mg m gasoline, the detection limits of VX and RVX vapor were increased to 20 mg m . Copyright © 2017 John Wiley & Sons, Ltd.
