• The end of the column does not protrude
from the top of the makeup gas adapter.
For most columns (outer diameter
> 0.15 mm), insert the column as far as
it will go into the gigabore liner. If using
a microbore column that passes com-
pletely through the liner, position the
column so that the total length from the
back of the capillary nut to the end of
the column is about 70 to 72 mm.
