Application range

♦ Determination of substances that are easily oxidized and reduced (carbon fiber electrode) 
♦ Determination of ethanol, saccharides, sulfides, amines and amino acids using metal electrodes (platinum wire electrodes) 
♦ Determination of substances without electroactivity by indirect electrochemical methods

Instrument characteristics

♦ Constant potential detection, high sensitivity, high resolution, fast separation, greatly saving solvent and sample consumption, 
♦ Simple and convenient operation 
♦ Set appropriate detection voltage to detect electroactive substances in the set range, good selectivity 
♦ Linear range Width, greater than three orders of magnitude 
♦ Small detection volume, direct contact with the measured electrode, no dead volume, single cell measurement 
♦ Unique detection cell design, so that the separation voltage is only added to the separation capillary section, overcoming the separation current to the detection current Interference 
♦ There are two types of detection on the column end and the column. 
♦ The electrode can be replaced at any time. The operation is simple and the electrode alignment problem is completely solved. 
♦ The circulating voltage pulse can effectively clean the electrode surface, reduce poisoning and restore activity.
