摘要
Abstract
Based on the principles of Volatile Organic Compounds (VOCs)adsorption on various sorbents,an air sample tube matching up to the Purge and Trap Concentrator for VOCs was developed.Cou-pled with Purge and Trap Concentrator and gas chromatography (GC),a comprehensive method to determi-nate the VOCs in ambient air was established.The results of all experiments indicated that the method was a-vailable for trace organic matter analysis,the method detection limits (MDL)of this method is up to 0.02 -0.1μg/m3 (when the sample volume is 1L)and average recoveries for the target analytes were in the range of 92.4% -98.2%.The method also showed good linearity (R2 >0.99)and precision (<9%)values.关键词
