“…Similar difficulties encountered for GC-MS characterization of expected Ru(CO) 5 species generated by PVG of Ru( iii ) in formic acid suggest the need for a more direct detection technique. Direct Analysis in Real Time (DART)/Orbitrap MS approaches possess a number of advantages for the detection of organometallic compounds 50 as well as identifying volatile analytes transported from GLS units used in vapor generation systems 51–54 and may offer a suitable solution to this conundrum, especially with advantage being taken of crossing the He DART beam with the effluent from a GLS within a T-shaped sample introduction device for improved efficiency/performance. 55…”

A liquid sampling-atmospheric pressure glow discharge (LS-APGD) ionization source operating at a nominal power of 30 W and solution flow rate of 30 µL min−1 and supported in a He sheath gas flow rate of 500 mL min−1 was interfaced to an Orbitrap mass spectrometer and assessed for use in rapid identification of inorganic and organic arsenic species, including As(III), As(V), monomethylarsonic acid, dimethylarsinic acid, and arsenobetaine in a 2% (v/v) nitric acid medium. Mass spectral acquisition in low-resolution mode, using only the ion trap analyzer, provided detection of protonated molecular ions for AsBet (m/z 179), DMA (m/z 139), MMA (m/z 141), and As(V) (m/z 143). As(III) is oxidized to As(V), likely due to in-source processes. Typical fragmentation of these compounds resulted in the loss of either water or methyl groups, as appropriate, i.e., introducing DMA also generated ions corresponding to MMA and As(V) as dissociation products. Structure assignments were also confirmed by high-resolution Orbitrap measurements. Spectral fingerprint assignments were based on the introduction of solutions containing 5 µg mL−1 of each arsenic compound.
