UV-Vis Detector Suited for In-line Flor Chemistry

Uniqsis’ Flow-UV is a cost-effective in-line UV-Vis spectrophotometric detector for flow chemistry applications.

Designed for use with almost any commercial flow chemistry system, the compact detector (18 x18 x 17 cm) fits conveniently into even crowded fume cupboards. Using the UV-Visible absorbance data from this detector allows dispersion experiments to be monitored in real-time, and enables product collection to be controlled according to the onset and decline of steady state conditions. With no moving parts, the device’s 3,648-pixel CCD array detector does not require calibration or routine servicing. In contrast to conventional Deuterium UV lamps, the Xenon flash lamp source has a lifetime of up to 10 years. Fiber optic waveguides connect the high pressure flow cell to the source and detector, thereby permitting the flow cell to be positioned virtually anywhere in the flow path. The flow cell itself utilizes 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 can be problematic.
