Holmium Oxide Test
This test verifies the calibration of the detector against the three wavelength
maxima of the built-in holmium oxide filter. The test displays the difference
between the expected and measured maxima.
spectrum.
The test uses the following holmium maxima:
• 360.8 nm
• 418.5 nm
• 536.4 nm

When to do the Test
• after recalibration,
• as part of the Operational Qualification/Performance Verification
• after flow cell maintenance or repair.
Interpreting the Results
The test is passed successfully when all three wavelengths are within ± 1 nm of
the expected value. This indicates the detector is calibrated correctly.
The test results are currently available on the Agilent ChemStation only.
N O T E
ChemStation revisions below B.01.xx show a limit of ± 2 nm. It should read ± 1 nm. If the
test shows a value greater than ± 1 nm, perform a recalibration.
