摘要
目的测定涂改液中10种卤代烃和苯系物。方法采用顶空气质联用法(选用甲醇作母液),对采样温度、平衡时间以及色谱条件进行了讨论,并对实际样品进行了测定。结果线性范围为2～1000μg/ml,最低检测浓度为0.05～0.10μg/ml,方法回收率为76.5%～110%,相对标准偏差为1.73%～7.75%。结论该方法可准确定性、定量测定涂改液中的卤代烃和苯系物。
Objective To determine halohydrocarbons and benzoid compounds in correction fluids.Methods Ten kinds of halohydrocarbons and benzenes in11commercially available correction fluid samples were detected by headspace gas chro-matography /mass spectrometry with methanol as the matrix.The sampling temperature,equilibrium time and chromatographic conditions of the method were investigated.Results The linear range,detection limit,recovery rate and relative standard devi-ation were2-1000μg /ml,0.05-0.1μg /ml,76.5%-111%and1.73%-7.75%respectively.Conclusion The method was ac-curate and suitable for the qualitative and quantitative analysis of halohydrocarbons and benzoid compounds in correction fluids.
