选用N，N-二甲基甲酰胺（DMF）为溶剂溶解样品，利用气质联用（GC-MS）分析仪对原料中各个组分进行定性分析，以吩GFDA1嗪为内标物，采用内标标准曲线法进行定量，建立了毛细管柱气相色谱法同时测定粗蒽中蒽和菲质量分数的方法。结果表明，粗蒽中各组分能较好地分离，并定性出22个组分。采用该方法对粗蒽样品测量所得结果为：蒽相对标准偏差为0.971%~1.544%，菲的相对标准偏差为0.836%~1.482%；蒽的回收率为98.98%~100.9%，菲的回收率为98.05%~99.57%。测定结果具有较高的准确度和精密度，该方法分析快速、灵敏、操作简单。

The capillary column gas chromatography method is established for simultaneous determination of anthracene and phenanthrene in crude anthracene through using N,N-dimethylformamide (DMF) as solvent to dissolve samples,carrying out qualitative analysis of each component in the raw material by GC-MS,using phenoxazine as internal standard and carrying out quantitative analysis by the internal standard curve method.The results show that the components in crude anthracene can be separated well and twenty-two components are identified.The relative standard deviations (RSDs) in detecting crude anthracene samples are 0.971%-1.544% for anthracene and 0.836%-1.482% for phenanthrene.The recovery rate is 98.98%-100.9% for anthracene and 98.05%-99.57% for phenanthrene.The method has the advantages of high accuracy,precision,rapid,sensitive,and easy to operate.
