UV/Vis Detector - Diode Array Detector (DAD)

UV/Vis Detektor Octave 4XE




   
 1 measuring cell, 4 wavelengths - simultaneous!







The UV-VIS detector Octave 4XE provides simultaneous detection at up to four different wavelengths ranging from 190 nm to 840 nm in a single channel.

The detector can also be used as Diode-array detector, for reliable, reproducible performance and minimal noise levels. Dual deuterium and halogen light sources provide sensitive detection over the wide range of wavelengths.

The UV/VIS is also usable as stand-alone-device. It has 4 analog outputs.
Several flow cells are available ranging in application from analytical to preparative (up to 500 ml/min). The cell is easy to replace.

The detector has a MathChannel-, as well as a Scan-option.
