LC-4C Amperometric Detector

 

The LC-4C is an analog detector specifically designed for LC/EC, with high current sensitivity, extensive filtering, offset and autozero. Detector control is via straight-forward front panel controls.

There are 2 channels available on the LC-4C - the detector channel, which applies a potential and measures the current response, and the generator channel, which can apply a potential. The detector channel is used in all experiments, whereas the generator channel is only used in experiments in which analyte is electrolyzed before reaching the detector electrode; for example, dual series electrode applications. If the current on both channels needs to be recorded, two LC-4C detectors can be combined, or an LC-4C can used in combination with a Petite Ampere. Alternatively, up to 4 channels can be monitored using the LC epsilon detector.
