Whatman石英濾膜1851-090——全國疾控中心承接大氣監(jiān)測*項*用濾膜??！
Air Sampling Filters空氣采樣濾膜- EPM2000
EPM2000是Whatman*門用于高空氣流量儀器PM-10取樣而開發(fā)，可以收集大氣中的微粒和氣溶膠。它由100％的純硼硅玻璃制成，可用于微量污染的詳細化學分析，特殊純度使化學痕量分析污染物時能夠達到低干擾或背景值。Whatman EPM 2000 被EPA選用作為范圍內(nèi)高流量空氣采樣儀的標準濾器。每一張都被單獨編號方便鑒別。
Quartz Filters石英濾膜– QM-A
Whatman石英濾膜由高純度石英微纖維制成，廣泛用于酸性氣體，堆棧，氣溶膠、煙囪，煙道方面的空氣污染監(jiān)測工作。特別適合于溫度達500℃時的PM-10的測試。Whatman石英濾膜所含堿金屬含量很低，“人造”硫酸鹽和硝酸鹽產(chǎn)物(來自二氧化硫盒二氧化氮)實際上減少了。QM-A根據(jù)EPA標準編號，在很多方面都可應(yīng)用。
