摘 要: 本文介绍一种简单、快速、灵敏、直接分析酒中游离脂肪酸的测定方法。用涂有OV-17熔融石英毛细管柱。选择游离脂肪酸质谱图中的基峰离子m/z 60进行SIM检测。定量测定了茅台酒、珍酒及鸭溪窖酒中十二种游离脂肪酸。 A simple, rapid and sensitive method for direct determination of free fatty acids in wineswas described by the authors. It is accomplished on a fused quartz capillary column coated withOV-17. The ion m/z 60 of the base peak in the mass of spectrum of C_4-C_(18) normal fatty acidswas used in GC/MS SIM. The contents of 12 free fatty acids in Maotai, Rare Distillate andYaxijiaojiu have been determined by this method.
