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
  
• Simplification of sample preparation
  
• Compatible with gradient HPLC

Compared with other detection techniques, such as photodiode array detection, the CoulArray® detector sets a new standard, allowing as much as three orders of magnitude improvement in sensitivity and simpler, math-free interpretation.
