CHELMSFORD, Mass. – The Coulochem III from ESA Biosciences, Inc., uniquely combines both coulometric and amperometric detection in a flexible high performance electrochemical detector system. In combination with ESA’s patented electrodes, the Coulochem III detector is the only electrochemical detector to offer redox capability in a single cell. Compatible with all HPLC columns and offering the widest choice of operating modes, the Coulochem III readily quantifies picogram to femtogram levels of oxidizable or reducible neurochemical, clinical, pharmaceutical, environmental, and biological compounds in a sample. Electrochemical detection is the acknowledged standard for highly sensitive and selective detection in HPLC. Advanced electronics give the Coulochem III market-leading stability and the lowest limits of detection possible. Coulochem III’s Integrated Organizer Module also saves valuable bench space and provides a protected, temperature-stabilized environment for columns and cells.
