A system is described for automating the direct gas chromatographic method for examining volatile profiles of vegetable oils. The system couples an external inlet device to a microprocessor‐based gas chromatograph for providing automatic control of the analysis cycle. Automation of the analysis cycle permits consistent control over sampling and analysis to obtain rapid and reproducible volatile profiles. Manual control is completely eliminated and the analyst is freed for other tasks. Volatile Profile Analysis (VPA) is employed to monitor “protected oil” quality of oils being processed, as well as in the finished product, in an objective manner, thus eliminating the subjectivity found in many flavor panels. Automated VPA is also a useful tool in modifying operating parameters when handling various oil types.
