General description

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

For more information about any of our adsorbents, please visit sigma-aldrich.com/adsorbents
Porous polymers are the most suitable adsorbent for applications based on the analysis of gases, acids, amines, organics of low carbon number and water.[1] 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.[2] 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). [3] Furthermore they are relatively inert and exhibit hydrophobicity.[4]

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).[5] 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).[6]

Footnote

HayeSep DB is a deactivated version of HayeSep D for use with basic compounds.
