General description
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.
Application
HayeSep®DB was used for analysis of nitrogen (N2), oxygen (O2), carbon monoxide (CO), nitric oxide (NO), nitrous oxide (N2O), and water vapor (H2O). HayaSep® DB in combination with HayeSep Q was also used for optimisation of a gas chromatographic method for trace gaseous impurities like dioxygen (O2), dinitrogen (N2), carbon dioxide (CO2), carbon monoxide (CO), sulfur hexafluoride (SF6), methane (CH4), nitrous oxide (N2O) and carbon tetrafluoride (CF4).
Footnote
HayeSep DB is a deactivated version of HayeSep D for use with basic compounds.
