Amperometric Detector

In the case of applied voltage, the amperometric detector detects the change of current caused by the redox reaction of the substance to be measured on the electrode surface. Amperometric detector is often used to analyze ions with low dissociation, which are difficult to detect conductivity detectors and have electrical activity.
