Use of a hand-portable gas chromatograph–toroidal ion trap mass spectrometer for self-chemical ionization identification of degradation products related to O-ethyl S-(2-diisopropylaminoethyl) methyl phosphonothiolate (VX)

Direct and Sensitive Detection of CWA Simulants by Active Capillary Plasma Ionization Coupled to a Handheld Ion Trap Mass Spectrometer

“…Although, there have been some reports on portable/handheld MS instruments for CWA detection, [8,9] all these systems suffer from a reduced selectivity and greatly decreased sensitivity compared with laboratory equipment. Some of these instruments feature MS 2 operation modes, which can compensate the lower resolution.…”

In‐field volatile analysis employing a hand‐held portable GC‐MS: emission profiles differentiate damaged and undamaged yellow starthistle flower heads

“…This unique volatile collection system was designed specifically for either dynamic or static headspace analyses (Asl‐Hariri et al, ) on an existing hand‐held portable GC‐MS system (Fig. ) (Smith et al , ). Its capability to distinguish volatile profiles emitted by undamaged and mechanically damaged plant treatments was evaluated under both cultivated and natural conditions.…”

On-Site Detection of Chemical Warfare Agents

“…The new type of the same instrument Hapsite ER, adopting Tri-Bed TA microconcentration, provides more excellent determination against ten CWAs ( Figure 60.5). Torion (American Fork, Utah) produces a fieldportable GC-toroidal ion-trap MS with a solid-phase microextraction sampling inlet for CWA and related compound determination in water samples (Smith et al, 2005(Smith et al, , 2011bContreras et al, 2008;Torion Technologies Inc., 2014).…”
