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]

应用

HayeSep D in combination with Tenax TA was used to analyze polar, low-molecular weight compounds, such as methanol and ethanol, and non-polar volatile organic compounds, such as benzene and toluene in a temperature-programmed desorption combined with mass spectrometry and Fourier transform infrared spectroscopy (FTIR).^[5]
