The Intensity Test is a test to measure the intensity of the detector lamp
and the transmission performance ("intensity") of the optics. The test is
available for the diode array detector and for the variable wavelength
detector.
1. Install the diagnostics cell in the detector.
2. Turn on the detector lamps (one or both) that you want to test.
3. Run the test from the Chromeleon software. Refer to the
Chromeleon Help.
4. Depends on the test result:
Test result
Passed
Failed
The Shutting Motor Test checks the mechanical stability of the shutter
motor and filter paddle. The test is available for the variable wavelength
detector.
1. Install the diagnostics cell in the detector.
2. Turn on the detector lamps (one or both).
3. Run the test from the Chromeleon software. Refer to the
Chromeleon Help.
4. Depends on the test result:
Test result
Passed
Failed
Action
Reinstall the flow cell of your application.
1. Diode Array Detector only: Check the diagnostics
cell for indications of contamination that prevent the
light to pass the cell unhindered. Repeat the test with
a clean cell. If the test fails again, replace the lamp.
2. Replace the lamp. Refer to the Operating Manual
for the detector.
3. If the test fails with the new lamp, the optics may
be defective. Contact Thermo Fisher Technical
Support.
