Uniqsis Ltd has introduced Flow-UV - an in-line UV-Visible spectrophotometric detector for flow chemistry applications.
Designed for use with almost any commercial flow chemistry system, the compact Flow-UV detector measures 18 x 18 x 17cm. Using the UV-visible absorbance data from a Flow-UV 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.
Its 3648 pixel CCD array detector has no moving parts so does not require calibration or routine servicing. The Xenon flash lamp source has a lifetime of up to 10 years.
Product features:
Fibre optic waveguides connect the high pressure Flow-UV flow cell to the source and detector, permitting the flow cell to be positioned virtually anywhere in the flow path.
The flow cell itself a short length of PFA reactor tubing so is 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.
Single button operation starts acquisition of a previously set up and saved method.
Up to 5 wavelengths can be selected over which to monitor a reaction, ensuring detector saturation is avoided.
Control software may be configured to automatically record a background spectrum at the beginning of each experiment.
