ECD-700

 

Electrochemical Detector

 

•  Add an ECD to any HPLC system

•  Two cells per detector possible 

•  Amperometric or coulometric cells 

•  Dual electrode

 

 

 

Eicom’s ECD-700 electrochemical detector offers superior stability and sensitivity. It relies on the same proven detector cell that’s in the HTEC-500. 

When the standard amperometric cell is fitted with the optional dual electrode, the ECD-700 can monitor two voltages at the same time. 

A second amperometric and coulometric cell can be added to the unit at any time.

 

 

 

 

Coulometry or Amperometry

 

Coulometry detects analytes as they pass through a porous electrode. Electrolysis tends to be near complete. In amperometry, the analyte

contacts the surface of a smooth electrode, and only a portion of the analyte is detected. Amperometry ultimately gives better sensitivity

due to its higher signal to noise ratio. For this reason, Eicom recommends using amperometric cells whenever possible.
