Determination of Halohydrocarbons and Benzoid Compounds in Correction Fluids by Headspace Gas Chromatogra-phy /Mass Spectrometry / 环境与健康杂志

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 were2-1000?g /ml,0.05-0.1?g /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.
