摘要
采用惠普HP19091F-413型0.32mm中口径毛细管柱 ,以肉桂酸乙酯作内标物 ,庚二酸二乙酯、辛二酸二乙酯、壬二酸二乙酯为标准物 ,直接进样 ,用FID检测 ,测定豉香型白酒中的二元酸二乙酯 ,结果庚二酸二乙酯、辛二酸二乙酯、壬二酸二乙酯的相对标准偏差分别为3.19 %、2.07 %和2.92 %。
The binary acids diethyl esters in liquor samples were determined with application of HP19091F-413 type, medium caliber capillary column with caliber 0.32 mm,ethyl cinnamate as inner standard material and diethyl heptanate diethyl suberate,diethyl azelate as standard materials by FID methods. And the relative standard deviations of diethyl heptanate,diethyl suberate,diethyl azelate are 3.19 %, 2.07 % and 2.92 % respectively.(Tran.by YUE Yang)
