Abstract

PURPOSE:To achieve a reduction in measuring time and effective utilization of a sample liquid, by performing a simultaneous analysis of anion and catio species with single injection of the sample liquid. CONSTITUTION:A sample liquid from a sample liquid tank 5 is introduced into a cation concentration column 42 to trap a cation specie in the sample. Then, the liquid flowing out of the cation concentration column 42 is introduced into an anion concentration column 43 to trag an anion specie in the sample liquid. Then, pure water for washing passing through a column 41 for refining pure water is introduced into the cation concentration column 42 while the remaining cation specie is carried to the anion concentration column 43. An eluate of cation is introduced into the cation concentration column 42 from an eluate tank 4 and then, the liquid flowing out of the column 42 passes through a cation separation column 44 and a removal column 51 to measure the cation specie with an electric conductivity detector 61. At the same time, the eluate from the eluate tank 6 is passed through the anion concentration column 43, an anion separation column 45 and a removal column 52 to measure the anion specie with an electric conductivity detector 62.
