5.3.2 Installing the New Sampling Needle
1. Move the Z-axis slide to the top of the carriage (see Figure 5-4 ).
2. Slide the sampling needle mounting block into the Z-axis slide,
ensuring that the new sampling needle (PEEK Sampling Needle Kit,
P/N 064511; Sampling Needle Kit–PTFE Lined and Sleeved,
P/N 064056) passes through the accessories plate, and secure the
mounting block with the knurled mounting nut (see
Figure 5-4 ).
3. Screw the sampling needle guide (P/N 064519) onto the underside of
the accessories plate.
NOTE The sampling needle guide ensures that the
PEEK needle does not bend or flex as it pierces
the septum in the sample container cap.
4. Route the tubing to the right, around the sampling arm housing.
