MSE PRO Electrochemical Detector for Chromatography System, Model 1

MSE PRO™ Electrochemical Detector for Chromatography System, Model 1

Overview

The MSE PRO Electrochemical Detector for Chromatography System Model 1 operates by facilitating an electrolytic reaction within the electrolytic cell. Under an applied voltage, it measures the change in current resulting from the redox reaction of the target substance on the electrode surface. This type of detector is commonly used to analyze ions with low dissociation degrees, which are challenging to detect using conductivity detectors but possess electrical activity.

Features

• Offers three detection methods—DC amperometric, pulsed amperometric, and integral amperometric—suitable for various sample types.
• Features an all-plastic flow path to minimize ion contamination.
• Delivers high sensitivity with an exceptionally low detection limit.
