Description

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. 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^®A is a copolymer of divinylbenzene and ethylene glycol methacrylate.

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

Application

HayeSep^®A maybe used for the measurement of carbon dioxide using the on-line gas analyser during the experimental set-up, to use activated carbon as a buffer in biofiltration of waste gases, to ensure a constant supply of contaminants like toluene to the bioreactor for effective biological waste-gas treatment.
