the installation tool, 26.
1 Slide a septum, interface column nut, and conditioned ferrule onto the
free end of the column.
The tapered end of the ferrule should point toward the nut.
2 Insert the column into the column installation tool.
Slide the column through until the end extends past the end of the tool.
3 Cut 1 cm off the end of the column (page 20).
4 Position the column so that 1 to 2 mm extends past the end of the tool.
Hand tighten the nut.
5 Slide the septum to touch the end of the nut.
The septum will help assure that the position is correct.
6 Use two wrenches to tighten the nut 1/4 turn.
The column should not slide when tugged gently.
7 Remove the column and nut from the installation tool.
The total length from the septum to the end of the column is 176 mm.
