Example spectra of the mass scans around m/z = 76, 78, and 80 Da/e measured on March 9, 2016. The points depict the pre-processed detector signal of row B. The error bars represent the statistical uncertainty. Individual fits of the detected species (green and black labels) are shown as dashed lines, while the solid line represents the cumulative fit. The signal of the detected CS₂ isotopologues (green label and shaded area) contain minor contributions from other CS₂ isotopologues (labelled in grey) that cannot be resolved with ROSINA/DFMS. Their calculated contributions (see Sect. 2.3) are subsequently subtracted from the integrated signal peak (shaded area). The species’ exact ion masses are shown as solid vertical lines.
