Porous polymers are the most suitable adsorbent for applications based on the analysis of gases, acids, amines, organics of low carbon number and water.[1] 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.[2]

應用

Porapak^™ QS treated with 2% phosphoric acid maybe used as column packing for gas chromatographic analysis of volatile fatty acids in rumen fluid.[3]

腳註

Porapak QS 是硅烷化的 Porapak Q，用于降低表面吸附。
