The Octave™ 4X UV/VIS Detector
Description
The Octave 4X UV/VIS Detector is engineered for seamless integration with Semba’s Octave Chromatography System. This versatile instrument provides simultaneous detection at up to four different wavelengths ranging from 190 nm to 840 nm in a single channel. The diode array design enables reliable, reproducible performance and minimal noise levels. Dual deuterium and halogen light sources provide sensitive detection over the wide range of wavelengths, and a built-in counter monitors work hours for both lamps.
The detector is controlled by the SembaView™ software application, which can display the output of two Octave 4X UV/VIS Detectors for simultaneous monitoring of two outlet streams (e.g. Extract and Raffinate). Several flow cells are available ranging in application from analytical (up to 50 ml/min, 5 mm path length) to preparative (up to 500 ml/min, 0.3 or 2.4 mm path length). The cell is easy to replace from the side of the detector.
