Routine and Preventive Maintenance
The Source Block Assembly _______________________________________________________________
Cleaning the Source Block
1. Sonicate the disassembled component parts (except the O-rings) first in
a 1% v/v solution of formic acid, then in water, and then in methanol.
Caution.
Ensure that the parts do not become damaged in this process. If
necessary, sonicate each part separately. In particular, ensure that the cones
are face-up at all times.
Caution.
Do not sonicate the O-rings, as the solvent and acid may damage
them.
Cleaning the RF Lens
Under normal working conditions, this procedure needs to be carried out
approximately once every 3 to 6 months. Refer to the
Maintenance
Schedule
WARNING.
Allow the source block and probe heater assembly to cool
before carrying out any maintenance.
1. Totally immerse the RF lens in a measuring cylinder or beaker of
[50:50] methanol:water and sonicate.
