ISO/TS 17383:2014描述了毛细管气相色谱法测定脂肪、油和脂肪混合物中单个甘油三酯的定性和半定量成分的程序。甘油三酯的分离基于它们的保留，这取决于甘油三酯中脂肪酸的碳数及其不饱和度。 ISO/TS 17383:2014适用于动物和植物脂肪，以及天然和合成甘油三酯的混合物，只要油脂肪酸成分不含亚麻籽油等高含量亚麻酸，且总链长不超过C60的总碳数。

ISO/TS 17383:2014 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. ISO/TS 17383:2014 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.
