For analyzing the test results, refer to the detector operating
manual.
Cell Test
Perform the Cell test to check whether the flow cell window is
clean.
The deuterium and tungsten lamps intensity is measured over
the detector wavelength range with the flow cell installed and
with the flow cell removed.
The test should be done with water in the flow cell.
When starting the test, the 1 nm slit is moved into the light path
and the gain is set to zero. The resulting intensity ratio
represents the amount of light absorbed by the flow cell. It is
displayed at screen and also listed in the maintenance audit trail:
