Holmium Oxide Test
This Holmium Oxide 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. The figure below shows a holmium test spectrum.
The Holmium Oxide Test is available in Agilent Lab Advisor (preferred tool).
The test uses the following holmium maxima:
360.8 nm
418.5 nm
536.4 nm

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.
