Liquid Handling Troubleshooting

Symptom

Probable Cause

Solution

1. Syringe makes a
clicking sound while
moving.

1a. Syringe is not calibrated.

1a. Run the Adjust Liq Syringe
diagnostic method (see

Section 4.2

1b. Syringe speed is too fast. 1b. Reduce the flow rate.

1c. Syringe is not securely
mounted.

1c. Check the syringe mounting.

1d. Defective syringe.

1d. Replace the syringe (see

Section 5.5

1e. Fluid path blocked at
valve, cartridge or disk, or
tubing.

1e. Inspect the fluid path and
correct the problem.

2. Incorrect solvent
dispensed.

2. Solvent lines placed in
wrong reservoirs.

2. Insert solvent lines into the
appropriate reservoirs and prime
the lines.

3. Syringe stalls.

3a. Flow rate is too high.

3a. Reduce the flow rate.

3b. Bad cartridge or disk.

3b. Replace the cartridge or
disk.

3c. 12-port valve problem.

3c. Run the 12-Port Valve Test
diagnostic method (see

Section 4.2

). If the problem

continues, contact Technical
Support for Dionex products.

NOTE:

Prime all solvent lines

before running the 12-Port Valve
Test.

4. Valves leak.

4a. Flow rate is too high.

4a. Reduce the flow rate.

4b. Valve fitting is loose.

4b. Make sure valve fittings are
securely finger-tight. If
tightening a fitting does not stop
a leak, replace the fitting (see

Section 5.1

5. Liquid volumes
delivered are incorrect.

5a. Flow rates are too high,
causing gas bubbles to form.

5a. Reduce the flow rates.
