| 摘 要： | 拟对用填充柱气相色谱法测油脂脂肪酸组成条件进行了优化。以菜油为例，用固定液为10％．DEGS和20％．DEGS两种比例的涂布量进行了测定和比较，并应用多因素等高线优选法，摸索了测定条件，最终使填充柱法不易分开的两组峰C18：0与C18：1，C18：3与C20：1得到分离，这对用该法测其他食用油脂的脂肪酸组成的气相色谱分析具有参考价值。

| Abstract: | This essay attempts to optimize the measuring conditions for the fat acid ingredients of the oil with gas chromatography of the packed column. Rapeseed oil is taken as an example for measurement and comparison between two different proportions ( 10% DEGS and 20% DEGS) with stationary liquid. The optimum seeding method of multifactor contour is used for figuring out better measuring conditions under which successful seperation of two groups of hard-to-devided peak(C18:0 and C18:1, C18:1 and C20:1) is finally realized. This contributes much to the measuring of fat acid ingredients of other kinds of edible oil with gas chromatography. |
