Amperometric detector, through the electrolysis reaction in the electrolytic cell, that is, under the action of external voltage, the current caused by the oxidation-reduction reaction of the substance to be measured on the electrode surface is used for determination. It is often used to analyze ions with low dissociation degree, difficult to determine by conductance detection and electroactive. There are three detection methods: DC Ampere, Pulse Ampere and Integral Ampere.
 
1. All-plastic flow path reduces the interference and pollution of dissolved ions.
 
2. High sensitivity and extremely low detection limit.
