Eric Frerot, Alain Bagnoud and Esmeralda Cicchetti Quantification of Hydrogen Sulfide and Methanethiol and the Study of Their Scavenging by Biocides of the Isothiazolone Family ChemPlusChem 79
What a stinker: For the quantification of hydrogen sulfide and methanethiol, a solid-phase microextraction (SPME) method with in-fibre derivatisation and GC–MS/MS analysis was developed and validated. It was used to demonstrate that biocides of the isothiazolinone family are able to trap these malodourous compounds (see figure). The mechanism of the scavenging reaction was studied by ultraperformance liquid chromatography (UPLC)-MS.
