Ion chromatography (IC) suppressor

An ion chromatography (IC) suppressor, comprising a first clamping plate, an intermediate plate, a second clamping plate, a first ion exchange membrane, a first electrode and a second electrode, wherein

• the first clamping plate, the intermediate plate and the second clamping plate are tightly buckled in sequence to compact the first ion exchange membrane between the first clamping plate and the intermediate plate and compact the second ion exchange membrane between the intermediate plate and the second clamping plate;
• a suppression chamber is formed between the first ion exchange membrane and the second ion exchange membrane, and the suppression chamber is filled with resin particles for ion exchange and support;
• the first electrode is embedded on a first side of the first clamping plate, wherein the first side of the first clamping plate is adjacent to the intermediate plate, and a first electrolysis chamber is formed between the first electrode and the first ion exchange membrane;
• the second electrode is embedded on a first side of the second clamping plate, wherein the first side of the second clamping plate is adjacent to the intermediate plate, and a second electrolysis chamber is formed between the second electrode and the second ion exchange membrane;
• the first ion exchange membrane and the second ion exchange membrane separate the suppression chamber, the first electrolysis chamber, and the second electrolysis chamber into three independent chambers;
• an eluent inlet and an eluent outlet are provided respectively at two ends of the intermediate plate, and an accommodating groove for mounting a screen plate is formed at each of a tail end of the eluent inlet and a head end of the eluent outlet;
• a first electrolyte inlet and a electrolyte outlet are formed on a second side of the first clamping plate, wherein the second side of the first clamping plate is away from the intermediate plate;
• and
• a second electrolyte inlet and an exhaust gas-liquid outlet are formed on a second side of the second clamping plate, wherein the second side of the second clamping plate is away from the intermediate plate.
