CI  Maintenance

To Clean the CI Source

5977B Series MSD Operating Manual

243

5

Ultrasonically clean the parts (each group separately) for 15 minutes. For 
dirty parts, use all three solvents in the order shown, cleaning 15 minutes with 
each of the following solvents:

•

Methylene chloride (reagent-grade)

•

Acetone (reagent-grade)

•

Methanol (reagent-grade)

For routine cleaning, cleaning with methanol is sufficient.

6

Place the parts in a clean beaker. 

Loosely

 cover the beaker with clean 

aluminum foil (dull side down).

7

Dry the cleaned parts in an oven at 100 °C for five to six minutes.

WARNING

Al

All of these solvents are hazardous. Work in a fume hood and take all 
appropriate precautions.

WARNING

Let 

Let the parts cool before you handle them.

NOTE

Take care to avoid contaminating 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.
