Description

Technical Field

[0001] This utility model relates to the field of ion chromatograph suppressors, and in particular to a novel suppressor. Background Technology

[0002] Suppressors are an important component of ion chromatography analysis systems. They are mainly used to reduce the background conductivity of the eluent, increase the conductivity of the analyte ions, and eliminate the influence of counterion peaks on weakly retained ions. They transform the high-conductivity eluent into a low-conductivity weak acid or water, thereby improving detection sensitivity. Depending on their structure, the most common suppressors on the market are resin-filled suppressors and screen-filled suppressors. Both have pores that penetrate the support material and ion exchange membrane. Due to the combined effect of these pores and the stacking relationship, the pressure in any channel of the suppressor increases during use, which can easily lead to liquid leakage from the interlayer or direct flow to the outside of the component, causing irreversible damage to the suppressor and affecting its service life.

[0003] The technical problem to be solved by this invention is how to design a technology to prevent liquid leakage from the inner liner jacket, thereby effectively improving the stability and service life of the suppressor. Utility Model Content

[0027] like Figures 1-7As shown, this utility model provides a novel suppressor, including a housing 1. Both sides of the housing 1 are provided with regeneration liquid delivery ends 2 and rinsing liquid delivery ends 3. An inner liner structure 4 is provided inside the housing 1. The inner liner structure 4 includes a base plate 401, a channel groove 402, an ion exchange membrane 403, a sealing element 404, a regeneration liquid grid 405, an electrode plate 406, a clamping plate 407, a clamping plate 408, a positioning hole 409, a positioning rod 410, and a fixing bolt 411. The base plate 401 is disposed inside the housing 1, and a channel groove 402 is formed inside the base plate 401, communicating with the rinsing liquid delivery ends 3. Ion exchange membranes 403 are provided on both the top and bottom of the base plate 401, and a sealing element 404 is provided on the side of the ion exchange membranes 403 that is far apart from each other. A regenerated liquid grid 405 is provided on the side of the seal 404 that is far apart from each other. An electrode plate 406 is provided on the side of the regenerated liquid grid 405 that is far apart from each other. A retaining plate 407 is provided on the top and bottom of the substrate 401. The retaining plate 407 is connected to the seal 404 and the electrode plate 406 respectively. A clamping plate 408 is provided on the side of the retaining plate 407 that is far apart from each other. Positioning holes 409 are provided at equal intervals on both sides of the substrate 401, the ion exchange membrane 403 and the seal 404. The positioning holes 409 are located on the outside of the channel groove 402. A positioning rod 410 is connected to the inner wall of the positioning hole 409. Fixing bolts 411 are provided at equal intervals on the outside of the positioning hole 409. The fixing bolts 411 pass through the substrate 401 and the retaining plate 407 respectively. The two clamping plates 408 are fixedly connected by the fixing bolts 411.

[0028] In the specific implementation process, it is worth noting that the shell 1 is the outer shell structure of the suppressor, used to protect the inner liner structure 4. The regeneration liquid delivery end 2 is used to connect to the ion chromatograph, allowing the regeneration liquid to be input into or output into the suppressor. The eluent delivery end 3 is used to connect to the ion chromatograph, allowing the eluent to be input into or output into the suppressor. The channel groove 402 inside the substrate 401 is connected to the eluent delivery end 3, and ion exchange membranes 403 and seals 404 are covered above and below the channel groove 402. The intermediate layer, machined using PEEK, is filled with ion exchange resin, maximizing the overall effect. To reduce the dead volume of the system and thus improve the performance of the ion chromatography analysis system, the positioning rod 410 is inserted into the positioning holes 409 on both sides of the substrate 401, ion exchange membrane 403, and sealing member 404. This positions the ion exchange membrane 403 and sealing member 404 relative to the substrate 401 and seals the channel groove 402, forming a channel for the eluent. The regeneration liquid grid 405, electrode plate 406, clamping plate 407, and clamping plate 408 are sequentially placed over the outside of the sealing member 404. A fixing bolt 411 is inserted through the clamping plate 408, the two clamping plates 407, and the substrate 401 at the top. It is then tightened and fixed to the clamping plate 408 located at the bottom, so that the clamping plate 408 and the abutment plate 407 abut and limit the electrode plate 406. Through the gap between the base plate 401 and the abutment plate 407, a regenerated liquid conveying channel is formed at the regenerated liquid grid 405. Through the cooperation between the housing 1, the regenerated liquid conveying end 2, the rinsing liquid conveying end 3, the base plate 401, the channel groove 402, the ion exchange membrane 403, the sealing element 404, the regenerated liquid grid 405, the electrode plate 406, the abutment plate 407, the clamping plate 408, the positioning hole 409, the positioning rod 410 and the fixing bolt 411, the positioning rod 410 locks the electrode plate 406. The positioning hole 409 allows the ion exchange membrane 403 and the sealing element 404 to seal the channel groove 402. The clamping plate 407 and the clamping plate 408 are used to clamp and fix the stacked structure, optimizing the stacked structure of the suppressor inner tank. This makes the structure of the suppressor inner tank more stable, improves the pressure resistance of the flow channels of the eluent and regeneration liquid, and ensures the stability and reliability of the suppressor under high-pressure working environment. This effectively prevents liquid from leaking from the inner tank interlayer, avoids perforation, cross-contamination and leakage, reduces the failure rate of the suppressor, effectively extends the service life of the suppressor, and improves the response value of the ion chromatograph.
