The BlueShadow detector 40D is a competitively priced IC/HPLC spectrophotometer for routine IC/HPLC applications including fast IC/LC methods. Besides offering excellent technical specifications, this robust detector features a highly flexible and compact design. The BlueShadow Detector 40D comes with an installed deuterium lamp which covers a wavelength range from 190 to 750 nm. This detector can be controlled with ClarityChrom® software, as well as from the touchscreen (stand-alone operation), via LAN, via RS-232, or through analog input/output. Due to a smart design the flow cell is easily accessible and can be changed very quickly. You can choose between a wide range of flow cells for analytical or preparative IC/ LC applications with flow rates from 10 μL/min up to 10 L/min.
