4 April 2013
In China civil building engineering is regulated by GB50325. The 2010 version emphasizes the analysis for benzene and TVOC. This application note demonstrates successful use of an Agilent 7667A mini Thermal Desorber and an Agilent 7820A GC System to determinate total volatile organic compounds for indoor air pollution. The results not only meet the requirements stated in GB 50325-2010, but also demonstrate excellent linearity, low carryover, and superior repeatability.
