Abstract
A method and apparatus using suppression of eluents for the analysis of anions or cations in ion chromatography. The invention relates to the intermittent use of the electric field during electrochemical suppression to minimize background noise during detection of the ionic species caused by the application of an electric field using an electrolytic membrane suppressor. Using this intermittent electrochemical suppression system allows the detection of the analyte in the absence of the electric field. The system finds particular benefit in reducing background noise created during electrochemical suppression, and in reducing the baseline interference when analyzing organic solvent-containing samples.
