CoulArray® - The Only Coulometric Array Detector for HPLC ESA's pioneering electrochemical technology has made possible the multi-sensor detector for HPLC. Measure multiple analytes simultaneously, including those that are chromatographically unresolved. Only ESA's unique coulometric array detection provides: Sensitivity to femtomole levels 3D resolution of co-eluting peaks Qualitative characterization of peaks Simpl…
Coulochem® III Electrochemical Detection Platform Both Coulometric and Amperometric detection Available with DC and/or Pulse/Scan modes (or both) Compatible with all HPLC columns Ideal for methods development or routine applications requiring high-sensitivity detection of a single or small group of analytes Sensitive, flexible and exceptional stabilty
Coulometric Electrochemical Cells- The Key to Enhanced Selectivity Coulochem cells are unique in their design, employing the patented ESA flow-through porous graphite electrode. These low-volume analytical cells contain two working electrodes. The high surface area of each electrode results in 100% reaction of the electroactive compound. The first (screening) electrode can be used to eliminate potentially interfering com…
