A new technique for sampling and analysis of atmospheric dimethylsulfoxide (DMSO)

A new technique based on the nebulization/reflux principle (Cofer chamber mist) has been used to sample atmospheric dimethylsulfoxide (DMSO). DMSO is reduced to DMS by sodium borohydride (NaBH4) and DMS is subsequently analyzed by gas chromatography. Recovery and reproducibility of the analysis are of the order of 90% and better than 10%, respectively. This analytical method has been also successfully applied to DMSO determinations in rainwater and aerosols.
