Whatman石英濾膜1851-865——全國(guó)疾控中心承接大氣監(jiān)測(cè)*項(xiàng)*用濾膜??!
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(cè)工作。特別適合于溫度達(dá)500℃時(shí)的PM-10的測(cè)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(lái)自二氧化硫盒二氧化氮)實(shí)際上減少了。QM-A根據(jù)EPA標(biāo)準(zhǔn)編號(hào),在很多方面都可應(yīng)用。
