The ESA CoulArray Detector is a coulometric multi-electrode electrochemical detector for HPLC. The instrument is designed to detect and quantitate trace levels of electroactive compounds in complex matrices. A typical application is the qualitative and quantitative analysis of a broad range of biogenic amines in biological tissues.
System includes:
- DG4 Degasser
- 2x 582 Solvent Delivery Module (or 584)
- 542 Autosampler
- (optional) Column heater
- 528 UV-Vis Detecetor
- CoulArray Organizer Module
- ESA/Dionex/Thermo 5600A CoulArray coulometric multi-electrode electrochemical Detector
- PC with data
