Mass chromatograms of cysteine-containing dipeptide authentic standards derivatized with monobromobimane. The y-axis (not shown) represents normalized intensity of ion count in the mass chromatogram monitoring m/z characteristic of individual target compounds, x-axis represents time in the analysis (0–20 min). The m/z transitions and structural formulae of each S-bimanyl derivative are indicated in the chromatogram
