Troubleshooting and Maintenance Guide

4
Abrasively clean the surfaces that contact the sample or ion
beam.
Use an abrasive slurry of alumina powder and reagent-grade
methanol on a cotton swab. Use enough force to remove all
discolorations. Polishing the parts is not necessary; small
scratches will not harm performance. Also abrasively clean
the discolorations where electrons from the filaments enter
the source body.
5
Rinse away all abrasive residue with reagent-grade
methanol.
Make sure
all
abrasive residue is rinsed way
before
ultrasonic cleaning. If the methanol becomes cloudy or
contains visible particles, rinse again.
6
Separate the parts that were abrasively cleaned from the
parts that were not abrasively cleaned.
7
Ultrasonically clean the parts (each group separately) for 15
minutes in each of the following solvents:
•
Methylene chloride (reagent-grade)
•
Acetone (reagent-grade)
•
Methanol (reagent-grade)
8
Place the parts in a clean beaker.
Loosely
cover the beaker
with clean aluminum foil (dull side down).
9
Dry the cleaned parts in an oven at 100 °C for 5–6 minutes.
WA R N I N G
All of these solvents are hazardous. Work in a fume hood and take
all appropriate precautions.
WA R N I N G
Let the parts cool before you handle them.
N O T E
Take care to avoid recontaminating cleaned and dried parts. Put on new, clean
gloves before handling the parts. Do not set the cleaned parts on a dirty
surface. Set them only on clean, lint-free cloths.
