Abstract

The invention provides an electroluminescent micro device based on ion exchange technology. An anode cavity, a cathode cavity, a sample channel and associated fixed connection devices are fixedly arranged in the electroluminescent micro device, wherein the sample channel, the anode chamber and the cathode chamber are respectively isolated by multiple ion units with opposite polarity or the same polarity. When the two ion exchange units have the same polarity, the electroluminescent micro device is characterized by an electroluminescent micro suppressor and is applicable to a capillary ion chromatogram system; and while the two ion exchange units have the opposite polarity, the electroluminescent micro device is characterized by an electroluminescent micro desalination device. Based on the electrodialysis principle and with the ion-exchange unit as the main functional part, the electroluminescent micro device is suitable for the capillary or nano LC (liquid chromatography), the pre-treatment device of the capillary ion chromatography samples or the mass-spectrometry joint, thereby realizing directional and effective removal of inorganic salts.

Description

【Technical field】 [0001] The present invention relates to the field of ion exchange technology, in particular to an electric microdevice based on ion exchange technology, which is suitable for capillary or nanoliter liquid chromatography, capillary ion chromatography sample pretreatment device or coupled with mass spectrometry (MS) interface, capillary ion chromatography suppressor. 【Background technique】 [0002] Capillary / nano LC (capillary / nano LC) or capillary ion chromatography (CIC) has become the most concerned analysis in recent years due to its advantages of high efficiency, solvent saving, and easy coupling with mass spectrometry (MS). One of the techniques. Biological samples are very suitable for capillary / nano LC or CIC analysis due to their complex matrix, few samples and expensive characteristics. However, biological samples usually contain a large amount of inorganic salts, which limits their effective chromatographic separation and subsequent detection by ...
