毛细管气相色谱测定芳烃组成

Determination of aromatic hydrocarbons by capillary gas chromatography

利用气相色谱快速、准确的分析特点。建立以SP-3400气相色谱仪及聚乙二醇毛细管柱快速分析芳烃类样品组成的方法,对同一样品测定的相对标准偏差为2.54%。此方法与QJ/NL08-59-89芳烃组成测定方法对不同的样品进行分析对比,结果表明,误差范围符合要求,分析速度快,操作简便,可以用于日常分析工作。

According to the speediness and accuracy of gas chromatography, a new method which can analyze the aromatic hydrocarbons samples quickly is established based on SP-3400 gas chromatograph and polyglycol capillary column, the relative standard deviations of the determination of same sample is 2.54%. Contrasting the new method and the QJ/NL08-59-89, the results show that the new method has advantages of high accurate, short time, simple operation, which can be used in daily analysis.
