补充资料：串级冲击式采样器(cascade impact sampler)
分子式：
CAS号：
性质：又称串级冲击式采样器(cascade impact sampler)。采集大气中不同粒度颗粒物的采样器。目前常用的有按颗粒物粒径大小分为9级(即9个粒径范围)的和5级的；前者称为安德逊(Anderson)分级采样器，后者称为安德逊大容量分级采样器。它们都是采用串级冲击(cascade impact)的原理设计而成的颗粒粒度分离装置，加上动力抽气泵组成。此外还有双分道采样器(dichromatomous sampler)可采集空气中小于15μm的颗粒物(称可吸入颗粒物)，并分成粗粒(2.5～15μm)和细粒(<2.5μm)两种。分级采样器收集的不同粒度颗粒物，可研究其中所含的化学物质和形貌的差异等，这些信息可作为鉴别污染来源、控制可吸入有害物质的重要依据。
