摘要
建立了利用气相色谱法测定洗油中α-甲基萘和β-甲基萘含量的方法。该方法以甲苯为溶剂采用HPINNOWax毛细管柱分离,氢火焰离子化检测器检测,外标法对α-甲基萘和β-甲基萘进行定量分析。该方法分离效果好,具有很好的准确度和精密度,整个试样分析时间不超过20 min。
Established the use of gas chromatography to determine the content ofα-Methylnaphthalene andβ-Method for determining the content of methyl naphthalene.This method uses toluene as the solvent and uses HP-INNOWax capillary column separation,hydrogen flame ionization detector detection,and external standard method forα-Methylnaphthalene andβ-Quantitative analysis of methyl naphthalene.This method has good separation effect,high accuracy and precision,and the entire sample analysis time does not exceed 20 minutes.
