毛细管柱气相色谱法测定修正液中有害物质
GC Determination of Harmful Substances in Correction Fluids with Capillary Chromatographic Column
摘 要
应用带有电子捕获检测器的毛细管柱气相色谱法分析了修正液中的有害组分,用对测定无干扰的溶剂n-庚烷稀释修正液样品并测定了其中的5种对人体有害的氯代烃,即二氯甲烷、三氯甲烷、四氯化碳、1,1-二氯乙烷及1,1,1-三氯乙烷.方法的检出限(3S/N)在0.001~10.0 mg·kg-1范围内,相对标准偏差(n=6)在2.45%~3.01%之间,标准加入回收率在97.6%~104.0%之间.

Abstract
Capillary column-gas chromatography with ECD was applied to the analysis of correction fluids for harmful constitutents.Sample of correction fluid was diluted with the non-interfering solvent,n-heptane,and 5 chloro-alkanes,namely,dichloromethane,trichloromethan,carbon tetrachloride,1,1-dichloroethane and 1,1,1-trichloroethane,which were harmful to human healthy,were determined with their detection limits (3S/N) in the range from 0.001 to 10.0 mg·kg-1.Tests for precision and recovery of the method were made,giving values of RSD′s (n=6) in the range of 2.45%-3.01%,and values of recovery in the range of 97.6%-104.0%.
