Microbeam analysis—Scanning electron microscopy with energy dispersive X-ray spectrometry—Morphology and element analysis of single fine particles in ambient air
全国微束标准化技术委员会(SAC/TC 38)
本标准规定了利用扫描电子显微镜(SEM)及能谱仪(EDS)观测环境空气中细粒子单颗粒形貌、定性分析元素，对环境空气颗粒物进行分类的方法。扫描电镜用于颗粒物的形貌观察和粒径测量，X射线能谱仪用于颗粒物主要元素定性分析。
本标准适用于在电子束轰击下稳定的颗粒物分析，不适用于硝酸盐、铵盐等热不稳定的颗粒物分析。
