Setting Up the Syringe Pump
Use the syringe pump to infuse samples into the API source, to infuse sample into the solvent
stream that is produced by an LC pump, or to load sample into the divert/inject valve.
1. Load a clean, 500 μL syringe with the sample solution, (1 in Figure 65).
2. Use a fingertight fitting to connect 4 cm (1.5 in.) of Teflon tubing to the (black) syringe
union adapter, (2 in Figure 65).
3. Hold the plunger of the syringe in place and carefully insert the tip of the syringe needle
(3) into the free end of the Teflon tubing. Then, place the syringe on the syringe pump.
4. Squeeze the syringe pump’s release button and slowly move the pusher block until it
contacts the flange on the end of the syringe plunger (4).
CAUTION Sharp object. The syringe needle can puncture your skin. Handle it with care.
IMPORTANT To minimize the possibility of cross-contamination, do the following:
• Use a dedicated syringe and length of PEEK tubing for the calibration solution and
another syringe and length of PEEK tubing for sample solutions.
• Wipe off the needle tip with a clean, lint-free tissue before reinserting the syringe into
the syringe union adapter assembly.
Note If necessary, use the syringe needle tip to slightly enlarge the opening in the end of
the Teflon tubing.
