System includes:
- DG4 Degasser
- 2x 582 Solvent Delivery Module
- 542 Autosampler
- (optional) Column heater
- Coulochem II Electrochemical Detector
- PC with ESA software
The control module allows the digital acquisition from all detector cells both in the DC mode and the Pulse mode, use of the digital inputs and outputs and supports the use of the Thermal organizer compartment. The user can easily create the detector control method from the Method Setup – Acquisition dialog, set the operation mode of the detector cells or create timed events in the Event Table. All of these parameters are then saved as a part of the method and can be added as a part of the report. Actual signals of each detector cell can be monitored and partly controlled from the Device Monitor window.
This Coulochem II Electrochemical Detector (ECD) is in good condition.
