摘　　要：以吹扫捕集装置Tekmar3000作为进样系统，稍加改装，利用色／质联用仪（GC／MS），通过极性和非极性两种毛细柱，对有人居住的密闭环境内挥发性有机化合物（VOCs）进行定性定量分析，确定出八个有机类别82种微量污染成分。并对该密闭环境的大气质量进行了初步评价，为气体净化提供了依据。82 volatile organic compounds (VOCs) of eight organic sorts in a space capsule where four peopIe lived were identified and quantified by GC/MS sampling system-Tekmar 3000 Purge & Trap Concentrator that has been slightly modified,and two kinds of capillary chromatography columns,polar column and non-polar column have also been used. The atmosphere toxlcology has been preliminarily assessed, and that provides the basis for purifying the hazardous gases in sealed space.
