11 Pump down the MSD.
12 Purge the calibration valve. See
After removing the calibrant vial, you must purge the calibration valve. Failure to do so

will result in severe contamination of the ion source and damage to the filament and
electron multiplier.
5975 Series MSD Troubleshooting and Maintenance Manual
Set the reagent gas flow to Gas Off.
Vent the MSD.
Remove the capillary column from the GC/MSD interface.
Pull the MSD away from the GC to expose the calibration vial and valve.
See page 103.
Loosen the collar holding the calibration vial in place. Do not remove the
collar.
Remove the calibrant vial. See
Fill the vial no higher than the bottom of the internal tube with fresh
PFDTD calibrant (8500-8510).
Replace the vial and tighten the collar.
Reposition the MSD next to the GC. See
