Each of the control chambers is positioned in an interlayer between two ion exchanging membranes of same type, the control chambers are filled with ion exchanging materials, and two control chambers are provided. A negative ion control chamber is arranged in the interlayer between two positive ion exchanging membranes, and a positive ion control chamber is arranged in the interlayer between two negative ion exchanging membranes. A middle isolation chamber is arranged between the adjacent positive ion exchanging membrane and the negative ion exchanging membrane and the middle isolation chamber is provided with electrolyte liquid. The utility model can simultaneously control negative and positive eluate, and can be used for material analysis for the negative and positive ions.
Description
The utility model relates to a kind of device that utilizes the ion exchange analysis material.
Existing ion chromatographic inhibitory column has only a kind of function, promptly can only suppress negative ion eluent or kation eluent.
The CN1003142B patent disclosure a kind of ion chromatographic inhibitory column of invention such as Xiamen University's Tian Zhaowu, it is according to the electrodialysis principle, under the acting in conjunction of electric field and film, ion is made directional migration, optionally remove the ion that the high electricity in the eluent is led, make eluent be converted into the material that low electricity is led by ion exchange resin membrane.It is made up of two ion exchange resin membranes and the inhibition chamber and the positive and negative utmost point chamber that are clipped in wherein.Its cylinder can use for a long time continuously, need not regeneration, need not to promote the propulsion system and the high voltage bearing packoff of regenerated liquid, and volume is little, and technology is simple.But it can only have the moon of inhibition or a kind of function of kation eluent, is used for the moon or cation analysis separately.
The purpose of this utility model is to propose a kind ofly can to suppress Yin and Yang ion eluent simultaneously, is used for the ion chromatographic inhibitory column of Yin and Yang ion analysis simultaneously.
The utility model comprises anode chamber, cloudy long-pending chamber, positive electrode, negative electrode, inhibition chamber, acidic aqueous solution is housed in the anode chamber, alkaline aqueous solution is housed in cathode chamber, suppress between the interlayer of ion exchange resin membrane that the chamber is positioned at two same types, form the material acid and alkali-resistance material that suppresses the chamber, suppress the indoor ion exchange material that is filled with, suppress the Vomitory that the chamber is provided with eluent and sample.Said inhibition chamber is established two, for negative ion suppresses the chamber, suppresses the chamber for kation between two anion-exchange resin membrane interlayers between two cation exchange resin membrane interlayers; Between a mutually close cation exchange resin membrane and anion-exchange resin membrane interlayer is the intermediate isolating chamber, and intermediate isolating is equipped with electrolyte solution in the chamber.
Negative ion suppresses the chamber and is filled with cation exchange material, and kation suppresses the chamber and is filled with anion-exchange material.Suppress the material of chamber and can use teflon.Electrode and direct supply are connected during work, and the yin, yang ion suppresses the chamber and is connected with yin, yang ion isolation post and electric conductivity detector respectively, and yin, yang ion eluent and detected yin, yang ion samples can suppress the chamber from the yin, yang ion simultaneously respectively and flow through.
The utility model can suppress yin, yang ion eluent simultaneously, is used for the yin, yang ion analysis simultaneously.Its principle is under the acting in conjunction of the ion exchange resin membrane of applying direct current electric field and two groups of same types (cloudy or sun), make ion make directional migration, remove ion opposite in the yin, yang ion eluent simultaneously, make yin, yang ion eluent convert low electricity simultaneously to and lead material with detected ion symbol.
Accompanying drawing is a structural drawing of the present utility model.
Embodiment: as shown in the figure, the utility model is provided with anode chamber (1), cathode chamber (2), positive electrode (7), negative electrode (8) and negative ion and suppresses chamber (9), kation inhibition chamber (10) etc.Acidic aqueous solution H is housed in the anode chamber

3Flow into negative ion respectively simultaneously and suppress chamber and kation inhibition chamber, when energized, then produce following reaction:
Negative electrode:
Anode:
Under electric field action, the H of anode chamber
+See through cation-exchange membrane (3) and enter negative ion inhibition chamber and CO
2- 3, HCO
- 3Ions binding forms H
2CO
3With Cl
-In conjunction with forming HCl, that is:
Negative ion suppresses indoor Na simultaneously
+See through cation-exchange membrane (4) and enter the intermediate isolating chamber.The OH of cathode chamber meanwhile
-See through anion-exchange membrane (5) and enter kation inhibition chamber and H
+Be combined into H
2O and Na
+Form NaOH,
That is:
Kation suppresses indoor NO simultaneously
- 3See through anion-exchange membrane (6) and enter the intermediate isolating chamber, the result can be simultaneously negative ion eluent Na
