The Agilent 1100 Series G1314A VWD is a high performance Variable Wavelength Detector, that can be used independently or added as a component to a 1100 HPLC system. This VWD employs a deuterium lamp that provides high intensity and a low detection limit, with a wavelength range of 190-600 nm. The optical system of this HPLC detector passes the light beam through a lens, holmium oxide filter, entrance slit, then to a spherical mirror where it bounces to a grating assembly, then a second mirror, to a beam splitter and finally the flow cell where UV absorption takes place and onto a sample diode to convert to an electrical signal. The grating assembly of this HPLC component uses a stepper motor, that allows for rapid changes of the wavelength to suit your application. The Agilent 1100 Series G1314A VWD is easy to access through a front panel, that allows you to quickly get to the lamp or replace a flow cell. This VWD can be operated through a controlling PC through the RS232C connection, or through the GPIB connector.
