Setting Up the Syringe
Y
To fill the syringe, connect it to the LC union, and insert it into the syringe pump
1. Fill a clean, 500-
μ
L Unimetrics syringe with your sample solution.
2. Connect a 4-cm (1.5-in.) length of Teflon tubing (0.03-in. ID
×
1/16-in. OD) with a
fingertight fitting (for a 10-32 receiving port and 1/16-in. OD tubing) and a ferrule to
the LC union. See
3. Insert the needle of the syringe into the segment of Teflon tube. Check that the needle tip
of the syringe fits readily into the opening in the free end of the Teflon tubing. If
necessary, you can enlarge the opening in the end of the tubing slightly.

Connecting an Infusion Line to the Grounding Union
Y
To connect an infusion line between the LC union and the grounding union
1. Connect a section of red PEEK tubing (infusion line) with a fingertight fitting and ferrule
(for a 10-32 conical receiving port and 1/16-in. OD tubing) to the free end of the
LC union.
2. Connect the other end of the infusion line with a fingertight fitting (for a 10-32 port and
1/16-in. OD tubing) and a ferrule to the grounding union.
