• Do not use cleaning supplies other than those specified in this procedure.
• If possible, prepare cleaning solutions just before cleaning.
• Prepare and store all of the organic solutions and organic-containing solutions in very clean glassware only.
Never use plastic bottles. Contaminants can leach from these bottles and further contaminate the mass
spectrometer.
• To avoid contaminating the cleaning solution, pour the solution on the wipe or swab.
• Allow only the center area of the wipe to contact the mass spectrometer surface. Cut edges can leave fibers
behind.
Tip!
Wrap the wipe around a thermally-bonded poly swab.
Figure 10-1 Example: Folding the Wipe
• To avoid cross-contamination, discard the wipe or swab after it has touched the surface once.
• Larger parts of the vacuum interface, such as the curtain plate, might require several cleanings, using multiple
wipes.
• Only dampen the wipe or swab slightly when applying water or cleaning solution. Water, more often than
organic solvents, might cause the wipe to deteriorate, leaving residue on the mass spectrometer.
• Do not rub the wipe across the aperture. Wipe around the aperture to prevent fibers from the wipes from
entering the mass spectrometer.
• Do not insert the brush in the aperture on the curtain plate or orifice plate.
Prepare the Mass Spectrometer
Note:
Mass spectrometers with a NanoSpray

ion source might require a full cleaning for best results. Contact
a local QMP or an FSE.
WARNING! Hot Surface Hazard. Let the ion source cool for at least 30 minutes
before starting any maintenance procedures. Surfaces of the ion source and
the vacuum interface components become hot during operation.
