An ion chromatography method for analysis of a plurality of analyte ions in a sequential flow of sample solutions, each analyte ion being of a common charge, said charge being one of positive or negative, said method comprising: (a) eluting at least one sample solution containing said analyte ions in the presence of an eluent comprising an electrolyte through separating medium effective to separate the analyte ions, thereby exiting as separation medium effluent, (b) flowing said separation medium effluent through an ion exchange resin bed suppressor containing ion exchange resin for suppressing said at least one sample solution, said electrolyte being converted to weakly ionized form by the non-precipitating ion retention on said suppressor ion exchange resin of the electrolyte ions of opposite charge to said analyte ions and said analyte ions being converted to acid or base form thereby exiting as a suppressor effluent, (c) analyzing said suppressor effluent by a detector to produce a first signal, (d) after completion of step (c), flowing a regenerant solution through said suppressor to regenerate in one step said suppressor ion exchange resin, the ratio of the time for step (c) to the time for step (d) being at least about 2:1, and (e) then, repeating steps (a)-(c) for at least a subsequent sample solution.
