Holmium Oxide Test
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. 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
When to do the Test
• after recalibration,
• as part of the Operational Qualification/Performance Verification procedure,
or
• after flow cell maintenance or repair.
