摘要：

The determination of the amount of trans unsaturated isomers present in collected fractions of unsaturated fatty acid methyl esters separated by gas liquid chromatography is accomplished by measuring the infrared absorbances of the collected peak at 10.36 and 8.55 μ. The ratio of these two absorbances is proportional to the trans unsaturation. The interfering polyester column bleed is removed from the collected peaks by collection on alumina and elution into the spectrophotometer cell with CS2. © 1969 The American Oil Chemists' Society.
