ABSTRACT:
An improved technique and apparatus for the independent measurement of anions and cations in solution, wherein the sample ions are chromatographically displaced in a plurality of ion exchange columns by an eluting ion which is or is made light-absorbing and wherein the sample ions are detectable from decrements in absorbance of the eluting ions as revealed by photometric monitoring; and the sample ions, cations and anions, are further detected independently by means for monitoring eluting anion and cation absorbance differences calibrated according to characteristic absorbance ratios of the selected eluting ion species at a plurality of wavelengths.
