ABSTRACT:
A modified quartz element having plasma and auxiliary gas ports, a upper chimney mount, a unique chimney holder and injection tube mount, and a compression plug is disclosed. The chimney holder and injection tube mount includes a specially machined groove so that a unique, double O-ring seal between the mount and the quartz element may be developed. The injection tube mount also includes a specially designed bore for receiving two O-rings so that the injector tube is supported in and sealed with the mount only through the use of resilient O-rings.
