Chromatographic Symptoms

General Information

When troubleshooting chromatographic symptoms, always
remember that the headspace sampler is only one part of
the system. Evaluate the whole system to isolate the
problem. Often, issues that appear in the chromatography
can be caused by a problem in one or more of the following,
in order:
• The sample.
• The sample preparation (including the consumable
hardware, such as vials, septa, syringes, solvents, and so
forth).
• The data system (acquisition setpoints, integration
parameters, peak identification settings, quantitation
settings, and reporting).
• The GC (method or hardware).
• The headspace sampler (method or hardware).
To troubleshoot chromatographic symptoms, begin
troubleshooting with the sample and sample preparation.
