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 多孔聚合物，被认为是第二代材料，批间一致，具有最小的收缩率和单体渗出。

Application
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).

Accurate chromosome segregation during cell division critically depends on error correction of chromosome-spindle interactions and the spindle assembly checkpoint (SAC) [1-3]. The kinase MPS1 is an essential regulator of both processes, ensuring full chromosome biorientation before anaphase onset [3, 4].
