Figure 23. Connection to the H-ESI or the low-flow H-ESI source
1. Use red PEEK tubing (1) (with a fingertight fitting) to connect the sample flow to the
grounding union (2 Figure 23).
2. Use red PEEK tubing (3) (with a fingertight fitting) to connect to the other end of the
grounding union (2).
3. Use a fingertight fitting to connect the other end of the red PEEK tubing (3) to the
H-ESI or the low-flow H-ESI spray insert (4).
Connecting the Sample Flow to the APCI Source
Connect the APCI spray insert to the sample introduction method. If you have the inlet
plumbed for H-ESI, you can leave the grounding union in place. You will not use it.
• Use tubing (red PEEK or natural PEEK (nano-Viper)) with a fingertight fitting to
connect the sample flow to the sample inlet of the APCI spray insert (Figure 24).
