The Flow-UV™ from Uniqsis is a universal in-line UV-Visible detector that sets a new standard for real time monitoring of continuous flow applications.

The compact, high-resolution Flow-UV™ CCD array detector does not require calibration or routine servicing. In contrast to conventional Deuterium UV lamps, the Xenon flash lamp source used in the Flow-UV™ has a lifetime of up to 10 years. Flow-UV™ is extremely easy-to-use.

Having set up and saved a method using the Flow-UV™ control software, pressing a single button is all that is required to start acquisition. To assure linearity of response, Flow-UV™ allows you to select up to 5 wavelengths over which to monitor a reaction thereby ensuring detector saturation is avoided. Absorbance is plotted against time using the system control software. The control software may be configured to automatically record a background spectrum at the beginning of each experiment.

Fibre optic waveguides connect a choice of Flow-UV™ high pressure flow cells to the source and detector thereby permitting the flow cell to be positioned virtually anywhere in the flow path. The flow cell uses a short length of PFA reactor tubing and is therefore not restricted to being located after the outlet back pressure regulator in the low-pressure region of the flow path where outgassing could be problematic.
