半岛bd体育手机客户端 说明

一般描述

Porous polymers are the most suitable adsorbent for applications based on the analysis of gases, acids, amines, organics of low carbon number and water. They are best suited for gas chromatography and are basically copolymers of polydivinylbenzene (DVB) which are very porous in nature ranging from mesoporous to microporous. Porapak?N is a porous polymer bead which provides significantly lower background at the carbon emission line. They are suitable in separating H2, CH4, CO2.
Porapak多孔聚合物是一种球形珠粒,具有一致的粒径、孔隙率和表面积,有助于确保分析的精确度和准确度。
