Test And Repair The Uv-Vis Detector - Gilson PLC 2050 User Manual

Test and Repair the UV-VIS Detector

Several models of uV detectors are available with the PLC 2050/2250/2500 Purification
Systems: uV monochromator single or dual wavelength, uV or uV-ViS PDa detectors
(DaD) 4-wavelength with different wavelength ranges (200–400 nm, 200–600 nm or
200–800 nm).
a deuterium lamp is used as a source of light. in versions up to 800 nm, a secondary halogen
lamp is used. the efficiency of the lamp and the cleanliness of the flow cell must be checked
periodically.
if efficiency of detection is unreliable, detector lamp wear could be to blame. Deuterium lamp
life can be checked with Gilson Glider Prep Software (GGP). from the GGP Software main
menu, select the ? icon, and then Information.
When disassembling or reassembling the detector, make sure that each component is clean
and take care that the system is in a clean environment.
refer to the UV-VIS Detector Service Guide for more information on detector testing, lamp
replacement, and flow cell cleaning.
