Abstract
Novel analytical and trapping methods applicable to the study of atmospheric sulphur compounds are described. (1) A gas chromatoeraphic method for the separation of dimethyl sulphide (DMS), dimethyl sulphoxide (DMSO), and dimethyl sulphone (DMSO2) are presented, alone with methods for concentrating these species from both the aerosol and gas phases. (2) A dual eluent ion chromatographic technique suitable for the separation and quantification of methane sulphonic acid (MSA) and other components of sea salt aerosol from each other is also reported.
