Thermo Scientific ESA Coulochem III Electrochemical Detector (ECD) P/N: 70-9142

Manufacturer: ESA / Thermo Scientific Model: esa Coulochem III Condition: Used Warranty: 30 day Test Performed: Listing ID# 37201

This Thermo Scientific ESA Coulochem III Electrochemical Detector is the standard for electrochemical detection that has greater sensitivity, selectivity, and as wide a dynamic range. 

Don’t let the name fool you, Thermo Scientific ESA Coulochem III offers you a choice – the only ECD system on the market that delivers the best in both amperometric and coulometric performance – giving you the capability you need for your specific application. The Coulochem III provides the options necessary for performing pulsed amperometric detection and cyclic voltammetry for maximum flexibility.

The most sensitive, sophisticated electrochemical detector available, the Coulochem III is ideal for use in methods development or for routine applications requiring high-sensitivity detection of a single or a small group of analytes.

The Coulochem III offers three operational modes:

  • DC Mode—for high-sensitivity analyses, electrochemical synthesis, and enhanced ionization
  • Pulsed Amperometric Mode—for carbohydrate analyses
  • Scan Mode—for characterization of an analyte’s electrochemical behavior
