摘要
提出采用HP 1毛细管色谱柱测定碳五馏分中微量阻聚剂二乙基羟胺组分的气相色谱方法。在本文提出的条件下,二乙基羟胺与其他组分分离良好,检出限低于20mg/kg,相对标准偏差为3.86%,结果准确可靠,方法满足控制分析的要求。
The method of a HP- 1 capillary gas chromatography is presented to determine the traces of diethylhydroxylamine which is a polymerization inhibitor in the C 5 fraction. Under the selected conditions, DEHA is separated with good resolutions. The detection limit is below 20 mg/kg. The method can be applied satisfactorily to the process analysis.
