LC Epsilon

The LC Epsilon electrochemical detector package is ideal for HPLC applications. BASi developed the first commercial electrochemical detector in 1974, and this is our7th generation electrochemical detector. The package includes the LC Epsilon, an electrochemical flow cell, an optional injection valve, and a CC-5 compartment. Electrochemical cells are very sensitive to stray electrical currents; so in addition to holding the electrochemical flow cell, injection valve, and chromatography columns, the CC-5 serves as a Faraday cage. It is available with 1, 2, or 4 channels and comes with ChromGraph software.
