Description

technical field

[0001] The invention relates to a chemical analysis instrument, in particular to a pressurized capillary electrochromatographic electrochemical detection device. Background technique

[0002] Pressurized Capillary Electrochromatography (p-CEC) is a new type of high-efficiency micro-separation technology that gradually emerges on the basis of the continuous development of Capillary Electrophoresis (CE) technology and the increasingly perfect liquid chromatography theory. . Compared with traditional capillary electrophoresis and high-performance liquid chromatography, p-CEC has outstanding advantages such as high efficiency, high separation rate, high selectivity, fast analysis speed, and low reagent consumption, so it has attracted more and more attention from the analytical chemistry community. The detection methods currently used are mainly ultraviolet absorption method, laser-induced fluorescence method, mass spectrometry and nuclear magnetic resonance met...
