摘要：近几年来，在贯彻GB11737-89、GB50325-2001 和GB/T18883-2002 的过
程中，对室内空气中苯的分析方法普遍感到存在不少问题。为此，我们在研制成
功的HL-800 二次热解吸仪上，采用将活性炭采样管直接二次热解吸，并与气相
色谱仪联用直接进样的方法，准确分析室内空气中苯系物。通过苯系物分析的重
复性和吸附/解吸效率试验，证实了该方法的先进性和实用性，圆满解决了快速、
准确、无二硫化碳污染进行分析室内空气中苯系物的方法。

Abstract: In the last few years, in the process of carrying through GB11737-89,
GB50325-2001 and GB/T18883-2002, many people thought that the analytical
method of benzene hydrocarbon in indoor air existed with not a few problems. For
this, we develop and manufacture the HL-800 twi-thermal desorption instrument. In
this paper, we adopt twi-thermal desorption/gas chromatography and confirm the
advancement and practicability of analyzing benzene hydrocarbon in indoor air with
active carbon tube by the repetition and adsorption/ desorption efficiency experiment.
It solves the method to analyze benzene hydrocarbon in indoor air fleetly, exactly and
without the pollution of CS2.
Key words: Benzene analysis; Active carbon tube; Twi-thermal desorption
