本文以GB/T27630-2011《乘用车内空气质量评价指南》中规定的部分VOCs为主要成分,以甲醇为溶剂,以标准限值的30%作为目标浓度,开发了一种简便、快捷、精准地配制特定浓度VOCs标准气体的方法,希望能对相关领域的计量检测工作起到帮助作用。一、材料与装置分析纯苯、甲苯、乙苯、二甲苯、甲醇,38.5%的甲 In this paper, some of the VOCs specified in GB / T27630-2011 Guidelines for Air Quality Assessment in Passenger Cars are the main components. With methanol as the solvent and 30% of the standard limit as the target concentration, a simple, rapid, Accurately formulating VOCs standard gas of certain concentration is hoped to be helpful to the measurement and detection in related fields. First, the material and equipment analysis Benzene, toluene, ethylbenzene, xylene, methanol, 38.5% of a
