Problems solved by technology

[0003] The present invention solves the problem that the existing resin-filled ion chromatography electrolysis self-regenerating suppressor has strict requirements on the number of filling materials in the suppression chamber, which causes internal cavities, affects the baseline and peak shape, easily causes interlayer liquid leakage, and more filling materials are destroyed. Extrusion, resulting in the technical problem of sealing difficulties, provides a resin-filled ion chromatography electrolysis self-regenerating suppressor with less influence on the performance of the suppressor by the amount of filling materials in the suppression chamber, and the liquid enters and exits from one side

Embodiment Construction

[0019] Description with reference to the accompanying drawings.

[0020]From top to bottom in the drawings are splint I1, ion exchange membrane 4, middle layer 3, ion exchange membrane 4 and splint II2, which are fixed together by fastening screws whose surface is coated with insulating material. In order to clearly illustrate the structure of the embodiment, the drawings of this embodiment show the splint I1, the ion exchange membrane 4, the intermediate layer 3, the ion exchange membrane 4 and the splint II2 separately, without drawing the fastening screws. The ion exchange membranes 4 between the splint I1 and the middle layer 3 and between the middle layer 3 and the splint II2 are both anion exchange membranes or cation exchange membranes, and in this embodiment are cation exchange membranes. Plywood I1 and Plywood II2 are made of reinforced nylon material with good resistance to organic solvents. There is a splint I electrolysis chamber 13 on the splint I1, and a splint ...

Abstract

The invention relates to a resin filling type ion chromatography electrolysis self-regeneration suppressor which is capable of analyzing materials by utilizing electrolysis, electro-osmosis and iron exchange and is used for eliminating countra-ion in a solution and lowering background conductance of a leacheate. The middle layer of the resin filling type ion chromatography electrolysis self-regeneration suppressor provided by the invention is fiber adding and hardening silicon sheet or bulk four-fluorine belt materials. In the vertical direction of a splint, two splint electrolysis chamber flow guide slots are staggered, and the liquid enters into the suppressor from one side, so that the technical problems that the middle layer of the existing resin filling type ion chromatography electrolysis self-regeneration suppressor has strict requirements to the filling materials are solved, the internal chambers are reduced, and base lines and peak shapes are influenced, so that the liquid among layers is easy to leak, and redundant filling materials are extruded so as to cause the sealing difficulty.

Description

technical field [0001] The invention belongs to a device for analyzing materials by using electrolysis, electroosmosis and ion exchange, specifically a resin-filled ion chromatography electrolysis self-regenerating suppressor. Background technique [0002] Suppressor is one of the key components of ion chromatography. The middle layer of the traditional resin-filled ion chromatography electrolysis self-regeneration suppressor chooses a support material with high pressure resistance and is not easily deformed, such as polytetrafluoroethylene, but the amount of filling material in the suppression chamber of the middle layer of this material affects the performance of the suppressor Big. Chinese invention patent, application announcement number CN 102253163 A "Electrochemical continuous regeneration of CO 2 "Suppressor" discloses a suppressor whose suppression chamber is made of polytetrafluoroethylene and filled with ion-exchange resin or ion-exchange fiber. Since the polyte...
