摘要
本文选用HP -FFAP石英玻璃毛细管柱 ,设置合适的载气流量、分流比及程序升温 ,用气相色谱法测定了啤酒中低沸点风味物质的含量。测定结果表明 ,此方法能够准确分离啤酒中的 6种风味物质组份。平行测定的相对标准偏差在 0 .2 0 % -3 .98% ,定量分析的精密度高 。
Using HP-FFAP glass capillary column and adopting carrier flow and process,a gas chromatographic method was performed for the determination of flavor substance in beer.The results showed the method can not only separate and determine six kinds of flavor substance from beer,but also is steady, rapid,precise,and practical.
