摘要

Abstract A sensitive analytical method for the quantification of malodourous hydrogen sulfide (H 2 S) and methanethiol (CH 3 SH) was developed and validated. The method consisted of solid-phase microextraction with concomitant in-fibre derivatisation of the mercaptan using N- ethylmaleimide. The adducts were analysed by GC–MS using a triple quadrupole in the selected reaction monitoring mode. The limits of detection of solutions of H 2 S and CH 3 ...
