Detector Technology, UV & UV-Vis

The multi-wavelength UV-DAD is suitable for small and large scale purification. A minimum threshold of
5 mAU ensures that very low sample concentration will be detected and collected. With a range from
-500 to 50,000 mAU, detector saturation is minimized and ensures no plateau shaped peaks. Collect
and/or monitor two wavelengths or scan a window or the entire range. The standard detector is a UV-DAD
200 - 600 nm, 200 - 840 nm is offered as an option. The flow cell is adjustable to increase or decrease sensitivity.

A Closer Look at Detector Technology

Adjustable Sensitivity

The design of the detector flow cell allows you to change the optical path length to increase sensitivity. The default configuration for the flow cell is set to the lowest sensitivity (0.3mm). At this setting detection limits of 10mg are easily achieved. In some cases a weak chromophore will require higher sensitivity.

To increase sensitivity, two additional settings are available. By re-arranging the flow cell windows the path length is easily adjusted.
