The anion suppression plate 12 is provided with a strip-shaped anion suppression chamber 32, the shared cathode and anode plate 13 is provided with a strip-shaped common cathode and anode chamber 33, and the cation suppression plate 14 is provided with a strip-shaped A cation suppression chamber 34 , a strip-shaped cathode chamber 35 is arranged on the cathode plate 15 .
所述阳极室31、共用阴阳极室33、阴极室35的两端均设置有对外开口。 Both ends of the anode chamber 31 , the common anode chamber 33 and the cathode chamber 35 are provided with external openings.
所述阳极室31、阴离子抑制室32、共用阴阳极室33、阳离子抑制室34、阴极室35内填充离子。 The anode chamber 31 , anion suppression chamber 32 , common anode and cathode chamber 33 , cation suppression chamber 34 and cathode chamber 35 are filled with ions.
所述阳极室31、阴离子抑制室32、共用阴阳极室33、阳离子抑制室34、阴极室35内填充的离子交换树脂厚度≤1mm。 The thickness of the ion exchange resin filled in the anode chamber 31 , anion suppression chamber 32 , common cathode and anode chamber 33 , cation suppression chamber 34 and cathode chamber 35 is ≤1 mm.
阳极板11、阴离子抑制板12、共用阴阳极板13、阳离子抑制板14、阴极板15、阳离子交换膜一21、阳离子交换膜二22、阴离子交换膜一23、阴离子交换膜二24通过绝缘材料或表面涂覆绝缘材料制成的紧固螺钉固定连接为一体。 Anode plate 11, anion suppression plate 12, common cathode and anode plate 13, cation suppression plate 14, cathode plate 15, cation exchange membrane 1 21, cation exchange membrane 2 22, anion exchange membrane 1 23, anion exchange membrane 2 24 through insulating material Or the fastening screws made of surface-coated insulating material are fixed and connected as a whole.
用作阴离子分析时，阳极室31和共用阴阳极室33起主要作用。接通电源阳极室31接通直流电源正极，在直流电场和阳离子交换膜一21的共同作用下，阳极室内的阳离子透过阳离子交换膜一21进入阴离子抑制室32，降低阴离子抑制室32的背景电导，从而大大提高了阴离子分析的灵敏度。进入阴离子抑制室32的阳离子，透过阳离子交换膜二22进入共用阴阳极室33被检测并除去。 When used for anion analysis, the anode chamber 31 and the common cathode and anode chamber 33 play a major role. Turn on the anode chamber 31 of the power supply and connect the positive pole of the DC power supply. Under the joint action of the DC electric field and the cation exchange membrane-21, the cations in the anode chamber enter the anion suppression chamber 32 through the cation exchange membrane-21, reducing the background of the anion suppression chamber 32 Conductivity, thus greatly improving the sensitivity of anion analysis. The cations that enter the anion suppression chamber 32 pass through the cation exchange membrane 22 and enter the common cathode and anode chamber 33 to be detected and removed.
用作阳离子分析时，与上述过程相当，阴极室35和共用阴阳极室33起主要作用。 When used for cation analysis, the cathode chamber 35 and the shared anode and cathode chamber 33 play a major role, which is equivalent to the above process.
同时用作阳离子分析和阴离子分析时，则相当于上述两个过程相加，而检测可通过对阴离子抑制室32和阳离子抑制室34的背景电导检测来完成。 When it is used for cation analysis and anion analysis at the same time, it is equivalent to the addition of the above two processes, and the detection can be completed by detecting the background conductance of the anion suppression chamber 32 and the cation suppression chamber 34 .
