A fully demountable torch can be adapted for another application by replacing the
injector and/or the outer tube with the configuration recommended for that
sample type. Refer to the Agilent Technologies website for ordering information.
Torch Assembly and Disassembly
Both the semi- and fully demountable torch models allow the outer/intermediate
tube-set to be separated from the base/injector for easier cleaning or replacement.
In addition, the fully demountable torch models allow the injector to be removed
from the base for easier cleaning or replacement.
WARNING
Hot Surface
The torch and torch compartment may become extremely hot during
instrument operation and remain hot so for some time after the plasma has
been switched off. Allow the plasma compartment to cool for at least five
minutes before accessing the plasma compartment. Allow the torch to cool
for two minutes before touching the outer tube or attempting to dismantle
the torch.
