The ECD-200 Electrochemical Detector provides high sensitivity for automated, analytical chromatography of electroactive compounds. With 0.05 to 200 nA/V detection range, this amperometric detector offers both high sensitivity and high selectivity.
The ECD-200 Electrochemical Detector is designed for repetitive applications and increased ease of use. Two methods can be stored.

• volt or nA/V output data
  
• volt or nA/V offset
  
• potential
  
• time constraint
  
• base line decay
  
• sensitivity
  
• chromatogram

Additional features of the ECD-200 include:

• Optimized flow path and low dead volume of the thin layer type electrochemical cell.
  
• An autozero function and easy-to-use software for automated, unattended operation.
  
• LCD screen that displays the real-time chromatogram and operating parameters.
  
• Control by computer or through RS-232 interface when integrated into a complete HPLC system.

Sensitive and selective

The ECD-200 provides sensitive, selective detection. The electronic transfer between electrode and compound in solution occurs only if the working potential is held at the right value to oxidize or reduce the compound; the detector is blind when the compounds react above this value.

Innovative electronics and specially designed cell

With a low dead volume, the cell maintains efficiency of the separation. The mirror polish of all cell parts eliminates hydrodynamic disturbances.
