Analysis of low concentration reduced sulfur compounds (RSCs) in air: Storage issues and measurement by gas chromatography with sulfur chemiluminescence detection

► Measure reduced sulfur compounds (RSCs) at low concentrations and low sample volumes. ► Improve the instrumental precision and demonstrate the reproducibility of the analytical method. ► Sampling in SilcoCan is suitable for the short-term storage of low level RSCs. ► Suitable for measuring RSC gas fluxes from natural soils.
