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
4) HPLC Grade Water
5) 6 N Nitric Acid followed by flushing with HPLC Grade Water
NOTE : Use only HPLC grade solvents.

4-4. Troubleshooting
Most problems with HPLC detectors are, in fact, caused by other parts of the system. Noisy and drifting
baselines, poor reproducibility in quantitative analysis, and similar problems are more often the result of
