5.2 Frequency of Cleaning
The frequency of cleaning the components of the MS detector depends on the
types and amounts of samples and solvents that are introduced into the
instrument. In general, for a given sample and ionization technique, the closer
an MS detector component is to the source of the ions, the more rapidly it
becomes dirty.
•
The ion optics and the mass analyzer become dirty at a rate significantly
slower than the API source. Refer to the topic Cleaning the Ion Optics
and Mass Analyzer Parts on page 5-10.
•
Clean the electron multiplier and conversion dynode whenever you
remove the top plate of the vacuum manifold by blowing them with a
clean, dry gas. Refer to the topic Cleaning the Ion Detection System on
page 5-15.
When the performance of your system decreases significantly because of
contamination, clean the components of the MS detector in the following
order:
•
Clean the API probe, spray shield, and ion transfer capillary
• Clean the tube lens and skimmer
•
Clean the ion optics and mass analyzer
CAUTION. As with all chemicals, solvents and reagents should be stored
and handled according to standard safety procedures and should be disposed
of according to local and federal regulations.
