YL9120 UV/Vis Detector
4-2-2. How to install a new Tungsten lamp
1) Insert the new lamp assembly onto the lamp housing on the right front panel.
2) Use the thumbscrews to attach the lamp assembly to the detector.
3) Connect the lamp lead to the lower of the two terminals in the lamp compartment.
4-3. Flow cell cleaning
We do not recommend disassembly of the flow cell assembly for routine cleaning purposes. Most of the
cell assembly can be adequately cleaned by flushing with several milliliters of appropriate solvent. We
recommend the following solvents for this purpose:
1) Methanol
2) Tetrahydrofuran
3) Methylene Chloride
L9120
4) HPLC Grade Water
5) 6 N Nitric Acid followed by flushing with HPLC Grade Water
NOTE : Use only HPLC grade solvents.
