Position the ferrule so that it is 17 mm from the column end. Place a small
mark (typewriter correction fluid is useful) at the back of the ferrule and,
making sure that the column is correctly positioned, insert the column end
into the adapter.

Screw the column nut on finger tight. Using a 5-mm wrench, tighten the
column nut 1/8- to 1/4-turn. Be careful not to overtighten.
Check the connections for leaks. If there are any leaks at the column
adapter, tighten it slightly more with the open end wrench provided.
Install ferrules on your packed column (See
column" on page 44).
If the capillary column hanger is installed, remove it. (See
capillary column hanger" on page
See Table 9 for fittings required. Install fittings as needed.
