摘　　要：利用气相色谱外标法测定饮料酒中的β-苯乙醇,采用HP-INNOWAX石英毛细管柱（30m×0.32mm×0.25um）进行检测,建立标准曲线相关系数为0.99999,检测限为0.5mg/L,回收率为99%~101%。测定结果证明该方法稳定,重复性好、回收率高。同时指出2-乙基正丁酸溶液（0.02%vol）不稳定,不适合作为标准物质。The beta-phenylethanol in alcoholic beverage was determined quantitatively by gas chromatography with external standard method.HP-INNOWAX quartz capillary column（30m×0.32mm×0.25μm） was used.A standard curve was constructed with a high correlation coefficient（R2=0.99999）.The detection limit and recovery rate were 0.5mg/L and 99%~101%,respectively.The results showed that the method was stable and repeatable with high recovery rate.Besides,it was found that 2-ethyl butyrate solution（0.02%vol） was unstable,and was not suitable as a standard.
