ECOM spol. s r.o. - Model ECDA2800 -UV-VIS PDA Detector

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.

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

• Wavelength range 200-800 nm
• Number of CCD elements 512 mathematically enhanced to 4 096 by sophisticated algorithm
