VUV-14D Fixed Wavelength UV-VIS Absorbance Monitor
The VUV-14D is a fixed wavelength light absorbance monitor designed to be used with ultra low volume sampling cells under flowing solvent conditions (i.e. chromatography). The VUV-14D series of detectors has a high resolution analog output with a 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.
* Constant temperature with standard 10 mm cell (air).
