Descrizione

Descrizione generale

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^™ R is a porous polymer composed of vinyl pyrollidone mainly suitable for the separation of ethers and esters.

Porapak porous polymers are spherical beads with consistent particle size, porosity, and surface area that help to insure analytical precision and accuracy.
