Maintaining Your GC
If the column id is greater than 0.1 mm:
Gently insert the column into the detector until it
a
bottoms; do not attempt to force it further.
Finger-tighten the column nut, then withdraw the column
b
about 1 mm. Tighten the nut an additional 1/4 turn with a
wrench.
If the column id is 0.1 mm or less position the column so it
extends above the ferrule by 48 mm (capillary optimized
fitting) or 68 mm (adaptable fitting). Slide the septum up to hold
the column nut and ferrule at this fixed position.
Capillary optimized fitting
48 mm
Insert the column into the detector. Slide the nut and
c
ferrule up the column to the detector base. Finger-tighten
the column nut until it grips the column.
Adjust the column (not the septum) position so that the
