Calibrating the PDA detector

Erbium calibration

Erbium calibration
Topic LCI-USG-0217, Last Updated 11/07/2024

Erbium calibration uses the on-unit erbium filter to recalibrate the instrument. Erbium calibration is most commonly done after replacement of an optical component.

You can perform an erbium calibration for the PDA detector from the system touchscreen.

Important:
  • A prior mercury calibration is a prerequisite to performing the erbium calibration.
  • Impurities in the flow cell can affect wavelength calibration. Ensure that the flow cell is clean before you perform calibration.
  • This procedure can adversely affect spectral library matching and peak purity analyses.
  1. From the touchscreen, tap HEALTH > Troubleshoot.
  2. Tap the detector icon.
  3. Tap Erbium Calibration, follow the on-screen prompts, and then tap START to begin the calibration process.
    The screen displays the calibration values.
  4. Tap DONE.
