Leírás

Általános leírás

HayeSep porous polymers, considered second generation materials, are consistent batch-to-batch, with minimal shrinkage and monomer bleed.

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. HayeSep^® has a high surface area owing to its micropores thereby making it a suitable candidate for separation of gases and volatile organic compounds (VOCs). Furthermore they are relatively inert and exhibit hydrophobicity. HayeSep N is a copolymer of poly(divinylbenzene-co-ethylenedimethacrylate).

Alkalmazás

HayeSep N was used as a adsorbent for analytical preconcentration of methane which contributes majorly to the greenhouse effect. It was found to have good adsorption capacity, highest overall selectivity and highest enthalpy for methane adsorption as compared to other adsorbents.
