Wavelength Accuracy - Internal - Thermo Scientific Orion AquaMate 8000 UV-Vis User Manual

Wavelength Accuracy - Internal

Thermo Scientific
This test locates the peaks of the internal xenon lamp (UV-Vis instruments) or internal
didymium filter (Vis instruments) and displays the expected and measured wavelengths for
the peaks.
• UV-Vis: A xenon lamp has strong, fundamental lines at 229 nm, 529 nm and 883 nm.
These lines are an essential property of xenon and serve as a fundamental standard.
• Vis: Didymium glass has strong transmission peaks at 585nm and 807nm. These peaks
are well characterized and suitable for use as wavelength standards.
When running the internal standard test, remember that:
• The wavelengths and tolerance values are preset and cannot be changed.
• The cell holder should be empty.
 To run the Wavelength Accuracy - Internal test
1. Highlight Wavelength Accuracy - Internal and press Enter.
2. Press Start Test.
The results indicate pass or fail for each wavelength.
If the test fails, follow these guidelines:
• Repeat the test twice to verify that the test is failing consistently.
• Contact technical support for more troubleshooting advice.
