ECD2800 UV-VIS detector

Information
ECD2800 click to zoom Catalog No.: ADA0000X


Variable wavelength 190 up to 800 nm, high-speed sampling 100Hz

Description

This detector has continuously variable wavelength in the range of 190-800 nm and noise level is ± 3·10-6 AU. Sampling adjustable up to 100Hz speed.

The unit may be used for analytical applications as well as for preparative/flash chromatography, according to the selected cell.

It is easy to operate; light intensities for reference and sample channels are available for detector diagnostics as well as information on lamp operating hours. The detector performs automatic wavelength calibration after the lamp has been switched on. High standard deuterium lamp in a special socket enables easy exchange.

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

Cell could be easily removed from the front of the unit. Flow cell AC05 is included as component of the detector.
