不同内径色谱柱对多环芳烃的分离效果研究徐长毫,曾小文(江西青春康源制药有限公司,江西分宜336600)摘要:多环芳烃(PAHs)是环境中重要的致癌物,为了分析不同孔径色谱柱对多环芳烃的分离效果,用C18硅胶填料分别装填三种不同内径的色谱柱(2.1×250mm,3.0×250mm和4.1×250mm),对多环芳烃分离柱效进行了比较,结果表明小孔径色谱柱(2.1×250mm)的理论塔板数较高,具有最高的色谱柱效,且流速较小,节约流动相;同时还获得了三种内径色谱柱分离多环芳烃的最适色谱条件。关键词:高效液相色谱法;多环芳烃;湿法装柱中图分类号:O657文献标识码:A文章编号:1671-380X(2022)12-0035-04SeparationofPolycyclicAromaticHydrocarbonsbyDifferentInnerDiameterColumnsXUChang-hao,ZENGXiao-wen(JiangxiQingchunKangyuanPharmaceuticalCo.Ltd,Fenyi336600,China)Abstract:Inthisstudy,theoptimalandmostsensitivechromatographicconditionsfortheseparationofpolycyclicar-omatichydrocarbons(PAHs)wereobtainedbycomparingthecolumnefficiencyofthreedifferentinnerdiameterchromatographiccolumns(2.1*250mm,3.0*250mmand4.1*250mm)filledwithC18silicagelfiller.There-sultsshowedthatthe2.1*250mmcolumnseparationofPAHSisthemosteconomicalandmobilephaseisthemostsensitive,meanwhile,thebestchromatographicconditionsforseparatingPAHsfromthreedifferentinnerdiameterchromatographiccolumnswerealsoobtained.Keyword...
