EI/CI GC/MSD interface (CI interface)

The CI interface mounts onto the side of the vacuum manifold, with one end in the
GC oven and the other in the MSD. Reagent gas is plumbed into the interface. The
tip of the interface assembly extends into the ionization chamber. A spring-loaded
seal keeps reagent gases from leaking out around the tip. The reagent gas is
plumbed into the interface body, and mixes with carrier gas and sample in the ion
source. This interface is also used for EI operation in CI MSDs.
