MS Maintenance Procedures
General Recommendations
There are a number of considerations to take into account when maintaining a
high-vacuum trace analysis instrument such as the 4000 MS. In particular,
considerable care must be taken not to introduce contaminants into the system.
Wash your hands before working on the system. Hand creams and highly
perfumed soaps should be avoided.
Gloves should be used when handling any parts that are internal to the analyzer.
Care must be taken when using gloves since many types of gloves can leave
chemical residues. Powder free Nitrile gloves are best to be used followed by lint-
free cotton or lint-free nylon gloves. Nylon and Nitrile gloves should not be used
to handle parts at elevated temperatures.
Keep all tools clean and free of grease or other contaminants.
Store sources and transfer line tips in the containers provided. The containers
are designed to be contaminant-free.
Take particular care to eliminate particles inside the vacuum manifold and on
sealing surfaces. Clean and filtered compressed air and chemical wipes (such as
Kimwipes®) can be used to remove such particles.
Cover open manifolds or exposed parts when they are not being worked on.
Chemical wipes or aluminum foil work well.
