The remainder of this section will address the less
frequent system checks.
7.1 How to clean the chamber, rotor, swings
and sample holders
As mentioned in section
6.2 Problem Prevention
,
TFA creep can give rise to debris being deposited on
the inside of the chamber and on the Quartz glasses.
Periodic inspection of the glasses, the inside of the
chamber and rotor is recommended to avoid an
unacceptable build up of potential contaminants.
Excessive build up of debris on the pivoting
faces of the sample swings and rotors, can give
rise to sample swings sticking in the out position
and result in product loss.
Routinely inspect the sample swings for free
movement and the inside of the chamber and quartz
glasses for build up of debris.
Clean with acetone taking care to avoid contact
with the outside paintwork and accessories of
the chamber.
Use the accepted Health and Safety precautions
when using acetone in this manner.
Maintenance:
Regular inspection and maintenance
of swings and sample holders should be performed
at least monthly. The following inspection routine is
mandatory following any tube breakage or solvent
spillage. Never use wet swings or holders in an
evaporator.
Inspection:
Visually inspect holders each month.
Debris should be cleaned off, especially any in the
sample holder wells as this may lead to glassware
breakage.
The number one cause of repeat
glassware breakage is glass fragments from a
previously broken tube. Sometimes the sample
sticks the glass fragments to the holder and it can be
difficult to remove. Residual solvent / sample -
should be cleaned off. Superficial surface damage
(e.g. scratches) will not affect the performance of a
holder or swing. Any structural damage, sufficient to
bend of deform any part of the swing, holder or rotor
- do not use - contact Genevac for evaluation.
Cleaning:
Loose dirt or debris can be removed
using a brush and / or airline. Adhered dirt / debris
or sample / solvent residue should be cleaned off
using methanol or acetone, soak swings or holders if
required. Swings / holders should then be washed in
clean water and fully dried before use.
