Anion exchange separation of polythionates and thiosulfate by HPLC (high-performance liquid chromatography) followed by differential pulse polarographic determination provides a systematic and sensitive analytical method for mixtures of these aqueous sulfur species. The time necessary for the partial separation of thiosulfate and polythionates is 12 min. Polarographic determination of each ion can be performed within 5-15 min except for the time necessary for sulfitolysis (20 min) with an error of less than +/- 10% for 10/sup -5/ to 10/sup -3/ M of thiosulfate and polythionates.
