Refill
1 Stop any tuning or data acquisition.
2 Set the reagent gas flow to Gas Off.
3 Turn off the MS electronics.
4 Cool down the GC/MS transfer line, the GC oven, and the GC inlet to
30 °C.
5 Uncoil enough slack from the capillary column inside the GC oven to allow
the GC to separate from the MS.
6 Move the GC away from the MS. See “To Separate the GC from the MS” on
page 79.
7 The CI vial is located on the side of the instrument near the transfer line.
8 Turn the CI vial collar counterclockwise to loosen it (Figure 17). Do not
remove the collar.
9 Pull the calibration vial out. You may feel some resistance due to the
O-ring around the vial tube section.
