Abstract:
The present invention pertains to a method of ion chromatography wherein a specialized electrodeionization (EDI) apparatus is used for simultaneous ion suppression of cations from a flowing base containing an anion sample of interest and ion suppression of anions from a flowing acid containing a cation sample of interest. The methods described herein allow for the ion suppression of samples containing chloride, nitrate, and other electrochemically active anions, as well as sodium, potassium, and other electrochemically active cations, without causing damage to the suppressor.
