Maintaining the Packed Column Inlet 6
Maintaining Your GC 117
To Install Ferrules on a Packed Metal Column
1 Gather the following:
• Wrenches
• Stainless steel male Swagelok fitting, 1/4- or 1/8-inch od
• Brass Swagelok nut and ferrule set (See “Consumables
and Parts for the Packed Column Inlet” on page 92.)
• Lint-free gloves
2 Verify that the column end is cut square and is free of burns
and deformation.
3 Secure the fitting in a bench vise.
4 Assemble a Swagelok nut and ferrules onto the column.
5 Fully insert the column into the vise-held fitting, then
withdraw 1–2 mm. Finger-tighten the nut.
6 Tighten the nut an additional 3/4 turn with a wrench (for a
1/8-inch column) or an additional 1-1/4 turn (for a 1/4-inch
column).
7 Unscrew the column nut from the vise-held fitting and
remove the column. Ferrules should now be set in place on
the column with the column end correctly positioned.
CAUTION
Wear clean, lint-free gloves to prevent contamination of parts with
dirt and skin oils.
