摘　　要： 报道了应用顶空气相色谱技术测定制浆造纸工业过程溶液中某些化学成分的浓度以及可挥发有机物气液相平衡常数的方法。这些方法可消除工业过程溶液中复杂母体对测定的影响,有利于解决制浆造纸样品分析中的一些问题。 This paper reviewed several headspace gas chromatographic （HSGC） techniques that can determine not only volatile species content but also their vaper-liquor equilibrium partitioning coefficients in the pulp and paper industrial samples with very complicated matrices. 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.
