To refill/purge the EI calibration vial
Materials needed
•
PFTBA (05971-60571)
Refill
1 Stop any tuning or data acquisition.
2 Turn off the MS electronics.
3 Remove the analyzer window cover. See “To remove the MS covers” on
page 80.
4 Turn the calibration vial collar counterclockwise to loosen it ( Figure 7 ).
Do not remove the collar.
5 Pull the calibration vial out. You may feel some resistance due to the
O-ring around the vial tube section.
6
Syringe or pipette PFTBA into the vial. With the vial vertical, the liquid
should be just below the end of the internal tube, approximately 70 µL of
sample.
7
Push the calibration vial into the valve as far as possible.
8
Withdraw the vial 1 mm. This prevents damage when you tighten the
collar.
