2.6.5 AVOID TOUCHING THE WINDOW
Recommendations :
□
Exercise extreme caution when working near the detector window. The collimator provides a
physical barrier to protect the window. Do not work with tools near the window.
□
If it is necessary to remove the collimator, the collimator should be removed and installed by a
trained technician so as not to touch the window or stress the end cap tip.
□
Do not direct pressurized gas or liquid streams at the detector window, for example in an
attempt to clean the window.
□
If necessary to clean the microscope chamber, retract or remove the detector using extreme
caution not to bump the detector tip or collimator.
2.6.6
LEAVE THE SEM IN HIGH VACUUM MODE
When not in use, If possible, leave the SEM in High Vacuum mode instead of in low vacuum or wet mode.
2.6.7 DO NOT EXPOSE THE DETECTOR TO EXTREME TEMPERATURES
Be mindful of conditions which may cause vapor condensation on the window or may cause the
temperature at the window to exceed manufacturer’s specifications. This may occur during a
microscope chamber bake or operation of a heat stage.
Recommendations :
□
If there is a possibility that the sample may emit vapors while in the sample chamber, especially
vapors acidic or alkaline in nature, fully retract the EDS detector to minimize the risk of
condensation on the detector window.
□
Take care when using a heating stage to follow manufacturer’s guidelines. Prior to using the
heat stage, confirm the EDS detector window type and temperature specifications as well as the
heat load on the EDS window during operation of the heating stage.
2.6.8 DO NOT EXPOSE THE DETECTOR WINDOW TO PLASMA
We recommend you do not expose the detector window to a plasma generated by a plasma cleaner.
