In older models, the cannula and the sample tube can be replaced separately.
1. Switch off the autosampler at the power switch.
2. Disconnect the connection between the sample tubing of the sampler and the ICP-
MS.
3. Carefully pull the sample tubing from the tubing guides on the autosampler.
4. Unscrew the cannula from the holder on the autosampler.
5. Unscrew the banjo bolt at the cannula and the sample tubing from the connecting
piece.
6. Only use a straight-cut, round and unpinched tubing end for the connection when
replacing the sample tubing. First push the banjo bolts and then one sealing cone
with the conical side onto the tubing and the cannula. The sealing cone and the
tubing or cannula end must be flush (see the figure below).
7. Screw the banjo bolts into the connecting piece hand-tight.
Install the cannula in the autosampler holder and thread the sample tubing through
the tubing guides at the autosampler (see section "Installation" p. 120).
