Electrochemical Detector

Short Description:

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

Technology Advantage

Unique noise reduction technology

Advanced Digital Filter (ADF), different from traditional filter time constant (FTC), has less signal loss in the process of noise reduction, which can let low frequency peaks pass, remove high frequency noise, improve signal-to-noise ratio and increase detection limit.

Unique structure of analytical flow cell

Central spray wall structure. The sensitivity of analytical flow cell can be continuously adjusted. The working volume can be continuously adjusted between 0 and 300 nl.One electrode can meet the application requirements of different sensitivity.

Built-in Faraday shielded temperature oven

Reduce static and unexplained interference and influence of temperature change, improve repeatability and stability.

Applicable to IC, HPLC and UHPLC

With DC ,PULSE and SCAN mode

The most sensitive electrochemical detector

Different flow cells to cover every application
