Visacon VUV-14D

The VUV-14D is a high sensitivity fixed wavelength light absorbance monitor designed for chromatography. It is a true dual beam instrument utilizing a deuterium light souce and narrow band pass filter arrangement that provides wavelengths from 190nm to 400nm.

The VUV-14D has a broad line of sample cells available. These include cells designed for on column capillary monitoring, standard and high flow 5 mm and 10 mm path length HPLC cells, and preparative LC.

High Sensitivity

The VUV-14D series detector has a high-resolution analog output with sensitivity range from 4.0 AU/V to 0.0005 AU/V and feature a state-of-the-art noise level of less than +/-0.00001 AU

Wavelength Selection

The deuterium lamp has a working wavelength range from 190 nm to 400 nm. Specific wavelengths are selected by using an interference filter. One filter is included with each detector.

Reliable, Rugged, Low Maintenance Design

The VUV-14 is constructed with a high reliability deuterium lamp, true double beam sample/reference light paths and a robust universal power supply. A rugged tactile feedback keypad for instrument control is standard.
