The Surveyor UV/Vis Plus Detector is a time programmable, variable-wavelength ultraviolet/ visible light absorbance detector. It operates in either the single or dual wavelength mode in the UV or visible ranges. The UV/Vis detector is a bench top unit for inclusion into the Surveyor LC System. The UV/Vis detector consists of a dual light source, an optical bench and dual photodiode detectors.
