Table 2.

Selected ion and associated signal-to-noise ratio (S/N) for trace level detection (deposited mass) of select inorganic oxidizers using negative mode JHTD-DART-MS in full scan mode (m/z 30 to m/z 500) with system parameters, Vapur: 4.5 L min−1, orifice 1 voltage (in-source CID): −20 V, N2 gas, 5.5 s burst of 3.25 A. S/N ratios and uncertainty expressed as the average and standard deviation of five replicate measurements
