ECDA2800 UV-VIS PDA Detector

8 channel 200-800
Is an analytical Diode Array Detector which allows measuring absorbance of eight wavelengths simultaneously in one cell just as measuring of whole spectrum (scan).
ECOM spol. s r.o.
Part number

This unit is used in liquid chromatography to verify analyzed samples by means of eight wavelengths or scanned spectra.

Noise level at 254 nm is ±5·10-6 AU with a test cell. High standard deuterium lamp in a special socket enables easy exchange from front panel. 

Output signal is available in both digital and analogue form. Detector could be controlled by Clarity or ECOMAC software.

Cell could be easily removed from the front of the unit. Three selectable flow cells AD02, AD05 and AD10 with optical path length 2.4, 5 and 10 mm. AD05 cell is included as component of the detector. Other cells on request.
The unit’s DAD (diode array detector) design offers many advantages:
continuous up to 100 Hz scan or absorbance measuring on eight wavelengths simultaneously
• wavelength setting from 200 up to 800 nm in increments of 1nm
• lamp work hours are counted using the built-in counter for both deuterium and halogen lamps
• the cell is easy to replace from side of the detector
Clarity PDA module support for 3D measurement
unit is controlled by RS232, Ethernet or USB interface
