Description

technical field [0001] The invention relates to an electrochemical suppression and resistance detection component, in particular to an integrated device integrating an ion chromatography electrochemical suppressor and a resistance detection cell. Background technique [0002] In order to realize the self-regeneration of the ion chromatography electrochemical suppressor, US Pat. No. 5,352,360 discloses an electrochemical self-regenerating ion chromatography suppressor (SRS), which realizes self-regeneration by electrolyzing water to generate regenerated ions without chemical reagents such as acid and alkali. [0003] The applicant disclosed in Chinese patent CN 02131711.9 an electrochemical ion chromatography suppressor with integrated electrode and electrolyte chambers, which adopts a two-electrode-one-chamber sandwich structure and a porous and corrosion-resistant electrolytic electrode. Due to the porosity of the electrode, it provides a space for the electrolyte to flow, ...
