The Coulochem® III Detector

CoulochemIII.jpg (58609 octets) pastilleThe Coulochem® III combines sensitivity, selectivity and stability to bring you an HPLC electrochemical detector that meets the demands of even the most complex analytical problems.

pastilleThe heart of the ESA system is the dual electrode coulometric electrochemical cell.
By using a combination of operational modes and specialized sensors, the Coulochem III delivers performance above that of fluorescence, UV and RI detectors.

pastilleThe Coulochem III Detector relies upon the electroactive nature of a large number of compounds that can be oxidized or reduced. Although fluorescence or UV detection may readily measure many of these compounds, liquid chromatography combined with electrochemical detection provides a more sensitive and selective alternative.

pastilleAccording to the cell type, applications are different and more specific.

  • The Model 5011 Analytical Cell is designed for high sensitivity applications at conventional potentials.
  • The Model 5010 Standard Analytical Cell for high potential applications.
  • The Model 5014B Microdialysis Cell is designed for the unique needs of the in-vivo microdialysis application.
  • The Model 5040 analytical Cell is an amperometric cell especially useful for applications such as pulsed amperometric detection of carbohydrates and measurement of acetylcholine.
  • The Model 5041 Microbore analytical Cell is designed to be used in microbore applications.
