Application Notes:

This fatty acid methyl ester mixture contains cis and trans isomers of several fatty acids in methylene chloride for the qualitative identification of unknowns. The product is a naturally occurring mixture from soybean and is an excellent standard for identifying unknown fatty acid isomers in samples. Because it is extracted from natural sources, relative peak sizes for the mixture may vary from lot to lot. This is a qualitative mixture and should not be used for quantitative purposes.
