Agilent 1200 G1314D VWD Varialble Wavelength Detector

Listing description

The Agilent 1200 Series Variable Wavelength Detector is designed for highest optical performance, GLP compliance and easy maintenance with:

deuterium lamp for highest intensity and lowest detection limit over a wavelength range of 190 to 600 nm
optional flow-cell cartridges (standard 10 mm 14 μl, high pressure 10 mm 14μl, micro 3mm 2μl, semi-micro 6mm 5μl) are available and can be used depending on the application needs (other types may be introduced later)
easy front access to lamp and flow cell for fast replacement
electronic identification of flow cell and lamp with RFID (Radio Frequency Identification) tag for unambitious identification, lamp information: part number, serial number, production date, ignitions, burn time cell information: part number, serial number, production date, nominal path length, volume, maximum pressure
Overview:
The optical system of the detectors radiation source is a deuterium-arc discharge lamp for the ultraviolet (UV) wavelength range from 190 to 600 nm. The light beam from the deuterium lamp passes through a lens, a filter assembly, an entrance slit, a spherical mirror (M1), a grating, a second spherical mirror (M2), a beam splitter, and finally through a flow cell to the sample diode. The beam through the flow cell is absorbed depending on the solutions in the cell, in which UV absorption takes place, and the intensity is converted to an electrical signal by means of the sample photo diode. Part of the light is directed to the reference photo diode by the beam splitter to obtain a reference signal for compensation of intensity fluctuation of the light source. A slit in front of the reference photo diode cuts out light of the sample bandwidth. Wavelength selection is made by rotating the grating, which is driven directly by a stepper motor. This configuration allows fast change of the wavelength. The cut-off filter is moved into the flightpath above 370 nm to reduce higher order light.
