Replace only parts mentioned in this document. For spare parts details, see
the Waters Quality Parts Locator on the Waters Web site’s Services & Support
page.
Recommendations:
• For optimal baseline stability, keep the detector door closed at all times.
• Filter solvents to prolong column life, reduce pressure fluctuations, and
decrease baseline noise.
• To conserve lamp life, extinguish the lamp while leaving the detector
running but idle. Note, however, that you should do so only when the
lamp will remain extinguished more than 4 hours.
• If you use a mobile phase with additives, flush it from the detector before
powering-off to prevent these adverse conditions:
–
Plugging of solvent lines and the flow cell
– Damaging of instrument components
– Microbial growth
Caution:
• To ensure optimum performance of the flow cell, ensure that eluent is
flowing before powering-on the detector. If, however, you must
power-on the detector before the eluent is flowing, extinguish the
lamp after establishing communications.
• To avoid damaging the detector or column, remove the column and
disconnect the detector before you flush the system.
