Long-chain unsaturated fatty acids (UFA) having up to six double bonds are derivatized to 2-substituted 4,4-dimethyloxazolines (DMOX) and then analyzed by combined in-beam electron impact (IBEI)-B/E-linked scan mass spectrometry. This technique provides highly characteristic mass spectra and may serve as an auxiliary means for direct structure determination of individual UFA in mixtures.
具有多达六个双键的长链不饱和脂肪酸(UFA)被衍生化为2-取代的4,4-二甲基恶唑啉(DMOX),然后通过束内电子轰击(IBEI)-B/E联动扫描质谱联用进行分析。该技术提供了高度特征性的质谱图,可作为直接确定混合物中单个UFA结构的辅助手段。
