摘 要: 以已酸乙酯作内标,正已烷为溶剂,用毛细管气相色谱法测定了蜡制品中香茅油的含量。该方法操作简便,样品只须用正已烷溶解即可测定,其检出限为0.10g·kg-1,相对标准偏差为0.01%-4.25%,回收率为91.2%-98.1%。 In this paper the citronella (oil) content of certain candle formulations was determined by using Capillary Gas Chromatography, with ethyl caproate (EC) as internal standard and hexane as the solvent. The limit of detection, relative standard deviation and recovery rate were 0.10 g·kg-1, 0.01 %-4.25 % and 91.2 %-98.1 %, respectively.
