The Surveyor UV/Vis Plus Detector is a time-programmable, variable wavelength ultraviolet/visible light absorption detector. It can operate in either single or dual wavelength mode in the UV or visible range. The UV/Vis detector is a tabletop unit that is integrated into the Surveyor LC system. The UV/Vis detector consists of a double light source, an optical bench and two photodiode detectors. Specifications:. Type: Specifications Light source: deuterium and tungsten lamps, reoriented.
