Description / Abstract:
This Technical Specification describes the procedure for the
capillary gas chromatographic determination of the qualitative and
semi-quantitative composition of individual triglycerides of fats,
oils, and fat mixtures. The separation of the triglycerides is
based on their retention depending on the carbon number of the
fatty acids in the triglycerides and their degree of
unsaturation.
This Technical Specification is applicable to animal and
vegetable fats, as well as to mixtures of natural and synthetic
triglycerides, as long as
-the oil fatty acid composition does not contain high
content of linolenic acid such as linseed oil and
-the total chain length does not exceed a total carbon
number of C60.
NOTE If quantitative results are expected, the response factors
of several triglycerides have to be checked as the increase of the
triglyceride unsaturation reduces the sensitivity.
