The GC/MSD Interface for a 7890B Series GC
The GC/MSD interface is a heated conduit into the MSD for the capillary column.
(See Figure 26.) It is bolted onto the right side of the analyzer chamber, with an
O-ring seal. It has a protective cover which should be left in place.
One end of the interface passes through the side of the GC and extends into the
oven. This end is threaded to allow connection of the column with a nut and
ferrule. The other end of the interface fits into the ion source. The end of the
capillary column extends slightly past the end of the column guide tube and into
the ionization chamber.
