Quick-Change Adjustable Torch Module
The Quick-Change Adjustable Torch Module consists of the torch assembly, spray
chamber, and nebulizer. These components are easily removed from the system for
regular inspection and maintenance. Normal wear on these components is shown by
metal or salt deposits on the quartzware or injector, glazed or devitrified quartz, worn
O-rings, or clogged nebulizer tips.
All the O-rings in the sample introduction system must be in place and be in good
condition. Otherwise, pressure leaks may occur, which can cause difficulties in
igniting the plasma and poor performance.
It is good practice to have spare parts available before removing any of the parts of
this module, particularly the torch, since it may be accidentally broken. Replacement
parts are listed at the end of this chapter.
Plasma Torch
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.
