• For the ESI probe, use two fingertight fittings and two ferrules to connect a length of
red PEEK tubing between port 3 of the divert/inject valve and the grounding union.
See Figure 36. To connect the other end of the grounding union to the ESI probe
sample inlet, follow the instructions in the Ion Max and Ion Max-S API Ion Source
Hardware Manual.

5. To connect the divert /inject valve to a waste container:
• Use a fingertight fitting and a ferrule to connect one end of a length of red PEEK
tubing to port 6 of the divert/inject valve.
• Place the other end of the tubing to an appropriate waste container.
To connect the inlet plumbing for an LC/MS system with an autosampler
1. Using an appropriate fitting and ferrule, connect one end of a length of red PEEK tubing
to the outlet of your LC system.
2. Using a fingertight fitting and a ferrule, connect the other end of the tubing to port 2 of
the divert/inject valve. See
