摘　　要：酸类气体(例如乙酸)的极性很强,在分析定量的过程中面临诸多问题,采用岛津公司的BID检测器,利用不同浓度[(10~1000×10^(-6))(摩尔分数)]的乙酸标准气,对乙酸的吸附性、进样重复性、定量线性、检测限、分析条件等方面进行了深入探讨,为酸类气体的分析提供一定的指导方法。Acid gases(such as acetic acid)have strong polarity and face many problems in the process of analysis and quantification.This study used BID detector made by Shimadzu and utilized different concentrations of acetic acid standard gas[(10~1000×10^(-6))(mole fraction)]for the discussion of adsorption,repeatability,quantitative linearity,detection limit and analytical conditions,to provide some guidance and analysis methods for the analysis of acid gases.
