The VUV-24 is a high sensitivity variable wavelength light absorbance monitor designed for chromatography. It is a true dual beam instrument utilizing a deuterium light souce and prism arrangement that provides wavelengths from 190nm to 400nm.

The VUV-24 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.

VUV-24

High Sensitivity

The VUV-24 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 a keypad input or RS-232 interface.

Reliable, Rugged, Low Maintenance Design

The VUV-24 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.
