Refer to Figure 6-33.
1. Place the mass spectrometer in S
2. Unscrew the ¼-28 PEEK fitting at the top of the ion source
housing.
3. Loosen the two clamps at both sides.
4. Gently lift and pull out the source housing.
1. Carefully place the ion source housing on top of the base
plate and line up with the rear electrical connection. Push
down until source chamber is seated evenly across the base
plate.
2. Lock down two housing clamps at both sides.
3. Finger-tighten the ¼-28 PEEK fitting at the top of the
source housing.
Plugging of the capillary (either in the ESI or APCI probe) causes
the pressure of the carrier fluid from the fluid interface to exceed
the maximum operating pressure indicated by Error 310 or Error
316. This error can be avoided by filtering directly injected
samples through a 0.45 µ syringe filter. To unplug the capillary,
complete the following:
1. Connect a 1 mL syringe, using adaptors, as needed to the
ESI or APCI capillary and push fluid through to remove
plug. If this procedure does not resolve the issue, an HPLC
pump can be connected to the inlet fitting.
2. If this procedure fails to unplug the capillary, refer the
instructions for the rebuild kit provided with your PurIon
system.
3. Reinstall the probe following the appropriate procedures
for your system.
