Gas Chromatography for the Quantitative Analysis of Flaxseed Oil Fatty Acids
Gas Chromatography for the Quantitative Analysis of Flaxseed Oil Fatty Acid Details:

Name: Capillary Column

Specification: 30m*0.32mm

Model: PEG-20M

Application: Determination of fatty acids in linseed oil gas chromatography

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. established a gas chromatography internal standard method for the quantitative analysis of fatty acids in edible vegetable oils. The method uses gas chromatography internal standard method, the internal standard is c17:00 methyl ester, the relative correction factor (RCF) of 17 fatty acid methyl esters is determined (based on 17:0, that is, f17:0=1), and 9 kinds of analysis Fatty acid composition and content of new commercially available vegetable oils (three kinds of tea oil, three kinds of olive oil, one kind of linseed oil, two kinds of safflower oil), and compare the fatty acid composition of nine kinds of oils, and analyze oil fatty acids Factors affecting content. Use "g/100g of edible food" to express the content of fatty acids. Results 17 fatty acid methyl esters are 8:0 methyl ester; 10:0 methyl ester; 12:0 methyl ester: 14:0 methyl ester; 16:0 methyl ester; 16:1 methyl ester; 18:0 methyl ester; 18 : 1 methyl ester; 18:2 methyl ester; 18:3 methyl ester; 20:0 methyl ester; 20:4 methyl ester; 20:5 methyl ester; 22:0 methyl ester; 22:1 methyl ester; 22:6 Methyl ester; 24:0 Methyl ester. The recovery rate of the experimental method is 85.06%, RSD=2.24%; precision is RSD=2.42%.
