摘    要:采用重量法对氮气中苯乙烯气体标准样品的制备方法进行了研究。依据国际标准化组织(ISO)颁布的"6142气体分析-校准气体混合物的制备-重量法"的标准方法,对标准气体在重量法制备过程中的定值分析、不确定度的来源、不确定度的估算以及不确定度的合成进行了阐述。制备的苯乙烯气体标准样品的量值与国外同类标准样品的量值具有可比性,能够满足环境恶臭污染物监测工作的需要。

关 键 词:环境  气体标准样品  恶臭污染物  监测

Abstract:The method for preparing standard gas of styrene in nitrogen at high pressure cylinder was studied. According to ISO6142 Gas Analysis-Preparation of Calibration Gas Mixture-Gravimetric Method,the source of certification and uncertainty of gravimetric method in preparing calibration gas were analyzed,and calculation of related combined standard uncertainty was assessed. Results indicated that concentrations of standard gas of styrene in cylinder were accurate,uniform and stable,which can fulfill monitoring requirement of odor pollutants absolutely.
Keywords:environment  standard gas  odor pollutants  monitoring
