Dionex ED50 Electrochemical Detector

ITEM: 23259 In Stock

The Dionex ED50 Electrochemical Detector measures current resulting from the application of potential (voltage) across electrodes in flow-through cells. Several different properties of the flowing solution can be determined, depending on the method by which the potential is applied and current is measured. The ED50 provides the 3 major forms of electrochemical detection: conductivity, DC amperometry, and integrated amperometry.
