Graphite Furnace Maintenance for the PinAAcle 900T/900Z
Cleaning the Graphite Tube and Contacts
Good, reproducible analytical results depend on good electrical contact between
the graphite contacts and the graphite tube. The contact surfaces of the graphite
tube and the contacts must be smooth and clean to allow good electrical contact.
After prolonged use the contacts may become contaminated with remnants of
samples and small particles of graphite. Even quite small particles can spoil the
contact and cause poor analytical results.
Every time that you open the furnace, clean the contacts.
Note
Do
not
touch the graphite tube or contacts with your fingers. Wear
contaminant-free gloves when changing the contact cylinders and graphite
tube.
