"The Agilent 1200 series Diode Array Detector control module has great optical performance and is easy to maintain. Easy front access lamp and flow cell for easy replacement. The DAD lamp emits light over 190 nm to 950 nm wavelength range. The module having inbuilt holomium oxide filter for wavelength accuracy. Two photo diode assemblies installed in the module one is sample diode and the other a reference diode. Control module having wavelength accuracy + or - 1 nm and for 6mm cell path length, maximum pressure limit is 400 bar. It can read multiple reads for single sample and allows to detect all the components in a sample with accurate results. "
