Superior Dual Lamp Stand Alone Multi Wavelength UV Detector for Liquid Chromatography and Process Technology


Variable multiple wavelength UV/VIS detector

Due to the Corona pandemic, this product is temporarily experiencing longer delivery times. With a quote you will of course receive an estimated delivery date.

 

The BlueShadow 50D offers high sensitivity and baseline stability for HPLC applications including fast LC methods. With its high speed scanning design, up to four different wavelengths can be monitored simultaneously while acquiring spectral data from 190 to 900 nm. Its remarkable values for noise, drift, and linearity are achieved through smart optical bench technology and the use of optimized components. The detector comes with an installed deuterium lamp  and an installed halogen lamp which are covering a wavelength range from 190 to 900 nm. This detector can be controlled with OpenLab® EZChrom Edition, ClarityChrom® software, as well as via the integrated display (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. A wide range of flow cells is available for practically any LC application, including micro flow cells for flow rates up to 10 μl/min and flow cells for preparative HPLC up to 10 l/min.
