Test Functions
Intensity Test
If the lamp fails in a single range there might be no reason to change the lamp if the
N O T E
application is not run in that specific range.
Redo the test with removed flow cell. If the counts increase drastically (more than a factor
of 2, then flow cell components are contaminated and may require maintenance/service.
If the intervals of lamp replacements are getting shorter, the Agilent service should check
the optical unit for contaminated components in the light path (coupling lens, source lens,
cell support assembly and flow cell windows).
