10 Adjust the column so it extends this specified distance from the end of the
GC/MSD interface.
For an EI XTR, SS, Inert or CI Source Installation (See Figure 5.), the column
extends about 1 mm from the column guide tube.
For an EI HES Installation (See Figure 6.), the column extends 4 to 5 mm
from the column guide tube.
Use the flashlight and magnifying loupe, if necessary, to see the end of the
column inside the analyzer chamber. Do not use your finger to feel for the
column end.
