Analysis of Vegetable Oil by GC/MS

A food service vendor wanted to know whether a new vegetable oil was similar to the vegetable oil that they had been using in the past. The oils were analyzed by direct injection using gas chromatography/mass spectrometry (GC/MS). The resultant gas chromatogram of the new vegetable oil (bottom figure) and the reference vegetable oil (top figure) are shown below. As seen in the figure, the reference vegetable oil contains additives of palmitic acid (retention time of 19.00 min), linoleic acid (retention time of 20.6 min), oleic acid (retention time of 20.7 min), and stearic acid (retention time of 20.9 min) which are not found in the new vegetable oil.
