Case Study: Gas Chromatography Mass Spectrometry Analysis (GC/MS) Testing
Below is an example of how Innovatech Labs, a leading contract laboratory, has used gas chromatography/mass spectrometry (GC/MS Analysis) to help a customer compare oil from a new supplier to oil from a previous supplier. Contact us today to find out how we can help with your specific materials analysis and needs.
Analysis of Vegetable Oil by GC/MS Testing
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 GC/MS testing resulted in a gas chromatogram of the new vegetable oil (bottom figure) and the reference vegetable oil (top figure), both 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.
