Syringe Troubleshooting Tips
Corrective Action
Possible Cause
Symptom
a. Wait at least 5 minutes for the syringe
drive pressure to stabilize. Larger-o.d.
lines might require more time.
b. Stop the syringe flow
• Replace the emitter tip
• Remove any constrictions or
blockages in the flow path
c. Replace the syringe.
d. Use a syringe with the specified volume.
a. The syringe drive pressure has not
stabilized.
b. Back pressure is excessive. This can result
from blockages in the emitter tip, sample
line, or union connections.
c. The syringe is leaking (inspect for
droplets along the body of the syringe).
d. The syringe volume is incorrect.
No spray
a. Lubricate the syringe pump shaft with
pump grease.
a. The infusion pump is faulty.
Inconsistent flow
a. Increase the flow rate, or use an LC
pump.
a. The syringe drive is unstable. (This occurs
at low flow rates.)
Sudden variations in
pressure, resulting in
low or erratic TIC
External Pump Troubleshooting Tips
Corrective Action
Possible Cause
Symptom
a. Refer to the guide for the external pump
to determine how to handle air bubbles
or blockages.
b. Locate the blockage and then remove it,
or replace the blocked component.
c. Refer to
.
d. Tighten all fittings. (Do not over-tighten.)
a. Air bubbles are present in the HPLC
system or sample.
b. The HPLC system or emitter tip contains
a blockage.
c. The HPLC system or union has a leak.
d. A fitting is loose.
