Abstract

The invention relates to a bipolar membrane acid-base liquid generating device for a chromatographic technology. In the invention, a principle of disassociating water with bipolar membranes is adopted, H<+> and OH<-> are generated by disassociating water on the bipolar membranes, the reaction equation is that: H2O=H<+>+OH<->, an ion exchange membrane is used through cooperating with an electric field to make ions to move to a specific part through directional migration and to be subjected to a chemical reaction to prepare the acid-base liquid with a preset concentration. Pure H<+> and OH<-> ions are generated by a system cooperating with the cation exchange membrane and the anion exchange membrane, the concentration of the acid and the base can be changed according to the change of the extraneous electric field, and the device is especially suitable for the ion chromatography field.

Description

Technical field: [0001] The invention relates to a bipolar membrane acid-base liquid generating device for chromatographic technology, especially an automatic eluent generating device for ion chromatography, and an ion suppressing device. Background technique: [0002] As an effective separation and analysis technique, ion chromatography has the following separation mechanism: the eluent and the sample to be tested flow into the separation column filled with ion exchange resin, and the ions to be measured form different chromatographic zones and flow out of the separation column. In the ion chromatography of the method, the effluent of the chromatographic column also passes through the suppressor for background suppression. However, in the application of ion chromatography, it is necessary to ensure that the ion concentration of the eluent meets the requirements at any time, so the actual operation steps are cumbersome. In addition, in the use of liquid chromatography, the ...
