环境空气取样和分析方法 方法17:环境空气中气态化合物的测定.直读腔衰荡光谱仪器法
This Standard sets out a method for determining gaseous compounds in ambient air using a cavity ring down spectroscopy method. The method applies to the determination of gaseous compounds in ambient air within the concentration range 0 up to 2000p.p.m. by volume, depending on the particular compound.
