Thread the column nut into the inlet adapter but do not 
tighten.
11 Adjust the column position so that the septum is even with 
the bottom of the column nut. Finger-tighten the column nut 
until it begins to grip the column.
12 Tighten the column nut an additional 1/4 to 1/2  turn with a 
wrench so that the column cannot be pulled from the fitting 
with gentle pressure.
13 Configure the new column. 
14 Condition the column per the manufacturer’s 
recommendation. (See To Condition a Capillary Column.)
15 Install the column into the detector. See:
