| General description: | Porapak porous polymers are spherical beads with consistent particle size, porosity, and surface area that help to insure analytical precision and accuracy. For more information about any of our adsorbents, please visit sigma-aldrich.com/adsorbe |
| General description: | 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. |
