Gas chromatography underpins fuel, petrochemical and environmental testing across South African refineries, gas plants and contract laboratories, yet many faults are traced to worn injection ports, contaminated columns or drifting detectors rather than the instrument software. This course builds practical skill in operating GC systems, diagnosing common faults, and applying preventive maintenance routines that keep uptime high in busy production laboratories.

Explain the principles of gas chromatography separation and detector selection for fuel and gas analysis.
Operate GC instrumentation including sample introduction, column selection and detector optimisation.
Diagnose common causes of peak tailing, ghost peaks, baseline drift and loss of sensitivity.
Apply a structured troubleshooting sequence to isolate faults in injectors, columns and detectors.
Perform preventive maintenance tasks that extend column life and reduce unplanned downtime.
Interpret chromatograms and quality control charts to confirm instrument performance before releasing results.
