摘要
为建立气相色谱法直接测定葡萄酒中的乙醇含量的方法，将样品稀释后直接进样，经过DB-FFAP毛细管色谱柱分离后用气相色谱FID检测器进行分析。在所建立的最佳实验条件下，葡萄酒中乙醇峰得到有效分离，线性良好，最低检出限为0．01％，相对标准偏差为3．6％-4．0％，平均回收率为90％-95％。说明该方法灵敏、简单易操作、准确可靠，用此法检测葡萄酒中的乙醇含量，结果满意。
To establish a method to determine ethanol content in wine by gas chromatography, the samples were diluted and were directly injected into gas chromatography, and separated by DB -FFAP capillary column and then detected by FID detector. Under these optimal experimental conditions, the methods had a wide linear range. The determination limits, the relative standard deviation and the rate of recovery are 0.01%, 3.6%--4.0% and 90%-95%, respectively. This method is sensitive, simple, and accurate. It could be applied to determine the ethanol content in wine.
