Determination of trace amounts of fatty acids in edible oils by capillary gas-liquid chromatographyFunded under: FP5
The effect of using different gas-liquid chromatography (GLC) hardware to quantify low concentrations of fatty acids was studied. A fused-silica capillary column was operated in two different chromatographs (A and B) that were interfaced to three different chromatographic data systems to process the flame ionization detector signals (systems A, B1 and B2). A test routine was developed that allowed the proper selection of peak processing parameters for the automatic recognition and integration of fatty acids occurring at trace levels. However, agreement of analytical results between the three analytical systems was not satisfactory; components at concentrations <0.10 g/100 g were noted, which could not only be attributed to the different use of GLC hardware. Attention should be paid to these technical restrictions when formulating product specifications based on fatty acid profile parameters.
