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:
• To Install a Capillary Column in the FID
• To Install a Capillary Column in the NPD
• To Install a Capillary Column in the TCD
• To Install a Capillary Column in the µECD
