e. Twist the sharpened end of the swab into the electron entrance hole on the CI ion
volume to clean out debris. You may need to use several swabs before the electron
entrance hole is clear of debris.
Figure 78. Cleaning the CI Ion Volume
Tip Clean the CI ion volume under a microscope to verify that you removed all
debris.
f. If you notice any scratches on the components, you may need to replace the
component. Scratches can affect the performance of your instrument.
2. Rinse the components with clean tap water. Use a toothbrush under a stream of water to
remove the aluminum oxide slurry. Do not let the slurry dry on the components because
it is difficult to remove. If the components still look dirty, repeat step 1.
3. Sonicate the components in warm detergent.
a. Use forceps to place the components in a beaker of warm detergent.
b. Place the beaker and its contents in an ultrasonic bath for five minutes.
c. Rinse the components with tap water to remove the detergent.
4. Sonicate the components in deionized water.
a. Use forceps to place the components in a beaker of deionized water.
b. Place the beaker and its contents in an ultrasonic bath for five minutes. If water is
cloudy after sonicating, replace the water with fresh water, and put the beaker and
contents in a ultrasonic bath again for five minutes. Repeat until the water is clear.
5. Use forceps to immediately transfer the components to a clean beaker of acetone.
