ABSTRACT:
A method and apparatus for the simultaneous analysis of borate and chloride ions in a liquid sample, such as a sample of nuclear reactor water, by ion chromatographic techniques are disclosed. The ion chromatographic system employed includes an exclusion column, an anion exchange column, and means for alternately directing effluent from said exclusion column to refractive index detecting means or void volume from the exclusion column and second eluent through the anion exchange column to conductivity detecting means.
