摘要
采用毛细管气相色谱法同时测定白酒中多种微量成分。色谱柱为DB-WAX(30 m×0.32 mm×0.25μm),采用程序升温,分流进样方式,检测器为氢火焰离子化检测器(FID)。在选定的色谱条件下,各种微量成分得到较好的分离,方法回收率在90.5%～100.8%之间,重现性好,准确度高。
Several trace compositions in liquor were measured simultaneously by capillary gas chromatography and the related technical conditions were summed up as follows： chromatographic column as DB-WAX （30 m×0.32 mm×0.25μm）, temperature programming, split sampling, and FID as detector. Under the above conditions, all trace compositions were separated successfully with the recoveries between 90.5 %～100.8 %. Such method had the advantages such as good repeatability and high accuracy. （Tran. by YUE Yang）
