Whatman石英滤膜1851-090——全国疾控中心承接大气监测*项*用滤膜！！
Air Sampling Filters空气采样滤膜- EPM2000
EPM2000是Whatman*门用于高空气流量仪器PM-10取样而开发，可以收集大气中的微粒和气溶胶。它由100％的纯硼硅玻璃制成，可用于微量污染的详细化学分析，特殊纯度使化学痕量分析污染物时能够达到低干扰或背景值。Whatman EPM 2000 被EPA选用作为范围内高流量空气采样仪的标准滤器。每一张都被单独编号方便鉴别。
Quartz Filters石英滤膜– QM-A
Whatman石英滤膜由高纯度石英微纤维制成，广泛用于酸性气体，堆栈，气溶胶、烟囱，烟道方面的空气污染监测工作。特别适合于温度达500℃时的PM-10的测试。Whatman石英滤膜所含碱金属含量很低，“人造”硫酸盐和硝酸盐产物(来自二氧化硫盒二氧化氮)实际上减少了。QM-A根据EPA标准编号，在很多方面都可应用。
