Cell Test
The cell test measures the intensity of the UV-lamp over the full wavelength
range (190 - 690 nm), once with the Max-Light Cartridge Cell installed, and once
with the Max-Light Cartridge Test Cell. The resulting intensity ratio is a measure
of the amount of light absorbed by the Max-Light Cartridge flow cell. The test can
be used to check for dirty or contaminated flow cell windows. When the test is
started, the 1-nm slit is moved into the light path automatically (G7117B only). On
the G7117A/G7117C, the 4 nm fixed slit is used.
This test should be performed initially with a new detector/flow cell. The values
should be kept for later reference/comparison.
5
Old UV-lamp.
Exchange the UV-lamp.

Defect optical unit.
If the test fails with Max-Light Cartridge Test Cell
and new UV-lamp, please contact your Agilent
service representative.
