6. Push the column up 1 cm and guide it into the inlet liner. Slide the nut and
ferrule up the column to the inlet liner. Adjust the column position so that
the correction fluid mark on the column is even with the bottom of the
column nut. Finger tighten the column nut until it starts to grab the column.
7. Tighten the column nut an additional 1/4 to 1/2 turn so that the column cannot
be pulled from the fitting when gentle pressure is applied.
8. After the column is installed at both inlet and detector, establish a flow of
carrier gas through the inlet. Heat the oven, inlet, and detector to operating
temperatures. Allow these to cool, and then retighten the fittings.
