HP (Agilent) 1050 Variable Wavelength Detector

Model 79853C

The 1050 Variable Wavelength Detector (VWD) is a detector of the modular type liquid chromatograph 1050 Series. This is a standalone grating/photodiode type general purpose detector. The performance and features match the requirements of the routine analysis and QC/QA analysis.
The 1050 VWD is a standard size detector of 1050 modular type LC series and can be build up with other LC modules, such as pump and automatic sampler. Since it is standalone type, it can be also used as an ordinary LC detector. It has a functional keyboard and 16-character fluorescent display which provides you easy operation.
