Interest in measurement of low concentrations of metal levels in suspended particulate matter has generated needs for high purity, low background filters. Several new types of filters are discussed with high purity compositions including glass fiber filters, fluorocarbon membranes and fabric-supported membrane filters. Air collection efficiencies are presented along with comparative analysis.
对测量悬浮颗粒物中低浓度金属含量的兴趣引发了对高纯度、低背景过滤器的需求。本文讨论了几种具有高纯度成分的新型过滤器，包括玻璃纤维过滤器、碳氟化合物膜和织物支撑膜过滤器。文中给出了空气收集效率以及对比分析。
