Troubleshooting

Symptom: Variability

Symptom: Contamination or Ghost Peaks

Symptom: Smaller or Larger Peaks Than Expected

Symptom: Sample Carryover

Symptom: No Signal/No Peaks

Correcting Syringe Problems

Correcting Sample Vial Delivery Problems

The information in this chapter will assist you in keeping the sampler running
smoothly.

The chromatogram is not satisfactory; clearly something is wrong. Use this
chapter to determine the probable cause and, in many cases, the cure for the
problem.

This chapter deals only with sampler-related problems. However, many of the
symptoms described here could also come from other sources, particularly the
stability of the gas chromatograph temperature and its gas supplies.

If you cannot correct the problem, obtain Agilent service.
