Beschreibung

Allgemeine Beschreibung

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.

Die porösen Porapak-Polymere sind kugelförmige Körner mit einer konstanten Partikelgröße, Porosität und Oberfläche, die analytische Präzision und Messgenauigkeit gewährleisten.
