ABSTRACT:
Anions in an aqueous solution can be quantitatively measured at a high sensitivity while controlling the electroconductivity possessed by an eluant to a low level, by the chromatographical analyzing method wherein a separating column, a cation exchange column and an electroconductivity detector are connected in the recited order, an aqueous solution containing an amine compound as an electron donor is used as an eluant, and a cation exchange column composed of the cation exchange resin substituted with a metal ion as an electron acceptor is used as the cation exchange column.
