5. Soak the ion transfer tube in a dilute solution of nitric acid to remove contaminants.
6. Sonicate the ion transfer tube in distilled water.
7. Clean the ion sweep cone by wiping the inside and outside with methanol and a Kimwipe.
8. Remove, clean with methanol, and inspect the Vespel
seated in the spray cone under the entrance end of the ion transfer tube. Replace it if necessary.
9. Reseat the O-ring in the spray cone.
10. Insert the ion transfer tube into the heater block. Rotate the tube as you insert it. After you
insert it, turn the tube clockwise until it is finger tight.
11. Align the gas inlet on the ion sweep cone with the sweep gas supply port on the ion source
mount. Firmly press the ion sweep cone into the ion source mount. See
