摘　　要：本文论述了带反吹热解吸直接进样检测室内空气TVOC浓度的实验方法,并对该方法进行了包括标准曲线、重复性、定量准确性和热解吸率在内的验证性试验和空气样品的平行采样分析。通过研究证明,此方法完全适合《民用建筑工程室内环境污染控制规范》GB50325-2001的试验要求。Room TVOC concentration testing method using direct specimen handling of thermal desorption with backflushing is introduced. A series of experiments is taken for the method, such as standard curve, repeatability, quantitative veracity and thermal desorption rate, and parallel sampling analysis to atmosphere sample is taken as well. The method is proved to be meeting the requirements of Control Standard of Room Environmental Pollution for Civil Architecture Engineering GB50325-2001 through research.
