Description

Technical field: [0001] The invention relates to an electrochemical detection device, in particular to an electrochemical chronopotential detector applied to liquid chromatography, ion chromatography, electrochromatography, capillary electrophoresis, microfluidic chip and other types of instruments. Background technique: [0002] In chromatographic analysis, it is divided into gas chromatography and liquid chromatography. Chromatography is a technique for analysis and detection after separation. Liquid-phase chromatographic detection is mainly divided into two categories, one is optical and the other is electrochemical. The existing electrochemical methods are divided into conductance, coulomb, ampere, integral ampere, pulse ampere, voltammetry and potential method. All methods except conductance and potential are essentially current detection methods. The essence of the conductometric method is to measure the resistance of the solution. The existing potential method refer...
