An intercalibration exercise carried out by the Universities of Stockholm [Sweden] and East Anglia [England, UK], for the determination of natural levels of dimethyl sulphide in aqueous samples, is described. Good agreement between the two groups was obtained for natural samples, but for cultures containing high numbers of marine phytoplankton some differences were observed. The problems associated with the analysis of samples with high densities of phytoplankton are discussed. Four calibration techniques were tested, and their relative merits are assessed.
