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.
Application
Porapak™ QS packed column maybe used for gas-solid chromatographic determination of moisture in lyophilized pharmaceutical products.
