ENRICHED ION CHROMATOGRAPH MEASURING METHOD AND ENRICHED ION CHROMATOGRAPH MEASURING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an enriched ion chromatograph measuring method and an enriched ion chromatograph measuring device capable of reducing a background noise resulting from an enriching column in analysis, suppressing a level change of the background, and facilitating quantitative observation of an ion component.;SOLUTION: This enriched ion chromatograph measuring method for supplying measuring object ions enriched by the enriching column to a separation column by eluant to perform analysis is characterized by having the first step for enriching the measuring object ions by the enriching column; the second step for allowing the eluant to flow into the separation column through the enriching column, and performing analysis of the measuring object ions; and the third step for allowing the eluant to flow into the separation column bypassing the enriching column, and continuing analysis of the measuring object ions.;COPYRIGHT: (C)2007,JPO&INPIT
