The ER825 C4D Detector is a flexible and configurable, 8 channel workstation. It supports capacitively-coupled contactless conductivity detection (C4D) for capillary electrophoresis, microchip electrophoresis, ion chromatograph/HPLC and flow injection analysis applications. In addition, signals from other sensors and analog voltages can be measured and recorded simultaneously.
The ER825 supports between one and eight channels of data. The number and type of channels must be specified when the unit is ordered. This enables the measurement of conductivity and other parameters such as pH, temperature, dissolved oxygen etc. at up to eight locations in a system. This makes the ER825 into a true Multichannel Configurable Chemistry Workstation.
