The Intensity Test measures the intensity of the deuterium lamp over the full VWD wavelength range (190 - 600 nm). The test can be used to determine the performance of the lamp, and to check for dirty or contaminated flow cell windows. When the test is started, the gain is set to zero. To eliminate effects due to absorbing solvents, the test should be done with water in the flow cell. The shape of the intensity spectrum is primarily dependent on the lamp, grating, and diode characteristics. Therefore, intensity spectra will differ slightly between instruments. The figure below shows a typical intensity test spectrum.
The Intensity Test is available in Agilent Lab Advisor (preferred tool).
The Agilent Lab Advisor and the Instant Pilot evaluate three values automatically and display the limits for each value, the average, the minimum and the maximum of all data points and passed or failed for each value.
Run the Intensity-Test with Agilent Lab Advisor (for further information see Online-Help of user interface).
