Title:

ION CHROMATOGRAPHY APPARATUS AND METHOD FOR REMOVING GAS PRIOR TO SAMPLE DETECTION

Document Type and Number:

Japanese Patent JP2012150124

Kind Code:

A

Abstract:

To provide a suppressor type ion chromatography method and apparatus for removing gas prior to sample detection.

In one aspect of the invention, by-product gas generated from suppression of a mobile phase is removed prior to detecting analyte ions at a detector. In another aspect, the amount of carbonic acid dissolved in a suppressed carbonate/bicarbonate mobile phase is reduced by removing carbon dioxide gas.
