摘    要:顶空气相色谱(headspace gas chromatography,简称HSGC)是将顶空样品预处理系统(headspace)和气相色谱结合使用的技术,具有简单、迅速、准确和自动化等优点,已经在商品检测、药品检测等常规检测中发挥重要作用。巧妙利用其顶空系统可以在化学分析测定中发挥更大的作用,能够测定挥发性化学物质的气液平衡常数(亨利常数)、无机盐的溶解度、高分子聚合过程单体含量等,还可解决化工工程样品分析中的复杂问题,以及应用于环境和其它工业过程化学成分含量的分析。

关 键 词:顶空  气相色谱  气液平衡常数

Abstract:Several headspace gas chromatographic(HSGC) techniques that can determine not only volatile species content but also their vapor-liquor equilibrium partitioning coefficients in the pulp and paper industrial samples with very complicated matrices were reviewed.The capability of HSGC for indirectly determination of non-volatile species through a phase conversion reaction method was also reported.Although the examples presented in this paper were more focused in the pulp and paper related application,HSGC technique has a great potential to be used for solving many very challenged problems in the other industries and research fields due to its accurate,rapid,simple,and automatic characteristics.
Keywords:headspace  gas chromatography  Henry constant
