Fig. 7.

Selective ion chromatographs (top) and relative peak areas of those SICs (bottom) of HS_nOH generation in reactions of H₂S with H₂O₂ (black) and MP-11 (red). The reactions done in the ratio of 1 mM H₂S and 1.2 mM oxidant in iP buffer pH 7, trapped by a bolus of iodoacetamide and dimedone (5 mM) after 5 mins. The peak heights and error bars derive from an average of three experiments.
