A simple gradient apparatus, consisting of a peristaitic pump in addition to a standard high-pressure pump, is described. The device is used to make a single-run ion chromotographic separation of sulfite, sulfate, and thiosulfate in less than 15 min. This separation required a step gradient with 4.8 mM NaHCO/sub 3//4.7 mM Na/sub 2/CO/sub 3/ as start eluent and 6.9 mM NaHCO/sub 3//8.6 mM Na/sub 2/CO/sub 3/ is final eluent when two (4 x 50) mm Dionex anion precolumns in series were used as separator. The eluent compositions were simplex optimized.
