ECD2800 UV-VIS Detector CE


These detectors with wavelength in the range of  190 - 800nm. They are derived from basic type ECD2600 /ECD2800. They are originally designed for use in capillary electrophoresis (CE).

Part number

Newly developed cell enables easy installation of quartz capillaries and minimizes interference by ambient light as well as mechanical shocks. The light is brought into the cell using optical fiber, which is focused in the center of quartz capillary for electrophoresis.

Detector is easy to operate, light intensities for reference and measuring channel are available for easy detector diagnostics as well as information about lamp operating hours. The detector performs automatic wavelength calibration after lamp start. High standard deuterium lamp in a special socket enables easy lamp exchange.

Output signal is available in both digital and analogue form. Detector can be controlled, programmed and used together with Clarity or ECOMAC software via RS232 or Ethernet interface.
