11. Carefully push the inner tube into the torch
body of the holder as far as it will go. Lightly
turn the tube while doing so to make sure that
the ground glass joint is sealed.
The injector tip must then be exactly flush with
the outer edge of the inner tube. If this is not
the case, pull the inner tube from the holder,
release the screw connection of the connecting
piece and push the injector into the holder as
far as it will go. Hereby a slight resistance
caused by the O-ring seal must be overcome.
Afterwards reinsert the inner tube and check
that the injector is seated correctly.
12. Insert the outer tube into the torch body. Make
sure that the ground joint seal is tight.
13. Install the torch and bonnet according to the section "Installation of the torch, nebulizer
with spray chamber and sample supply" p. 34.

Replacing the torch body
The torch body of the demountable torch only needs to be replaced if it is cracked. It does not
need to be cleaned together with the other glass components of the torch.
1. Dismantle the torch as described in the section "Cleaning the demountable torch" p. 46.
2. Unscrew the white Allen screw on the front of
the holder which secures the torch body in the
correct position.
3. Unscrew both connections for the argon gas
supply at the rear of the holder.
4. Pull the torch body from the holder. Remove
any shards if necessary.
