WARNING
AVERTISSEMENT
This procedure is intended PerkinElmer Service Representative.
Cette procédure est destinée au représentant du service
PerkinElmer.
The analyzer element of any high performance quadrupole mass spectrometer is, of
necessity, a finely machined assembly that has been precisely aligned using specialized
equipment.
Under no circumstances should you ever disassemble the main mass analyzer
assembly.
The mass spectrometer is fitted with prequads that act as a prefilter assembly designed
to protect the analytical quads by intercepting the majority of any contamination. As a
consequence, the analytical quads should never, under normal working conditions,
require cleaning. Occasionally, it may be necessary to remove the prefilter rods for
cleaning. The need to clean these rods is usually indicated by poor peak shape or loss
of resolution, although other more likely causes, such as source contamination, should
be eliminated first.
