22 Performance VerificationWavelength Accuracy - InternalWavelength Accuracy - InternalThis test locates the peaks of the internal xenon lamp (UV-Vis instruments) or internaldidymium filter (Vis instruments) and displays the expected and measured wavelengths forthe 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 peaksare 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 test1. 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.Thermo Scientific Orion AquaMate 7000 Vis and Orion AquaMate 8000 UV-Vis 109
