The plasma torch assembly is comprised of a quartz torch with an inner quartz tube,
injector, and adapter for securing the injector into an inlet in the spray chamber.
The injector supplied is an alumina injector with a 2.0 mm inner diameter. Other
injectors available include alumina injectors of different inner diameter for varying
sample flow rate, quartz injectors for different sample types and sapphire injectors
for silicon applications. For more volatile solvents, use a smaller diameter injector.
Regularly inspect the torch glassware and aerosol injector tube. The glassware
should be clean, with no traces of deposits or signs of melting. Give particular
attention to the inner quartz tube. Before removing the torch for cleaning, be sure
to have a spare torch available, in case it should break.
The quartz torch is shown in the next figure.
