PEG-20M毛细管柱 亚麻籽油脂肪酸定量分析的气相色谱

名称：毛细管柱

规格：30m*0.32mm

型号：PEG-20M

应用：亚麻籽油中脂肪酸的测定 气相色谱法

浩瀚色谱（山东）应用技术开发有限公司建立食用植物油脂中脂肪酸定量分析的气相色谱内标法。方法采用气相色谱内标法,内标物为c17:00甲酯,测定17种脂肪酸甲酯的相对校正因子（RCF）(以17:0为基准,即f17:0=1),分析9种市售新型植物油脂（三种茶油、三种橄榄油,1种亚麻籽油,2种红花油）中脂肪酸构成和含量,并对9种油中的脂肪酸构成进行比较,分析油类脂肪酸含量的影响因素。以"克/100克可食部食物"来表示脂肪酸的含量。结果17种脂肪酸甲酯为8:0甲酯;10:0甲酯;12:0甲酯:14:0甲酯;16:0甲酯;16:1甲酯;18:0甲酯;18:1甲酯;18:2甲酯;18:3甲酯;20:0甲酯;20:4甲酯;20:5甲酯;22:0甲酯;22:1甲酯;22:6甲酯;24:0甲酯。实验方法的回收率为85.06%,RSD=2.24%;精密度为RSD=2.42%。

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%.
