Abstract
A separation process includes producing low temperature glassy carbon from an aromatic oligomeric precursor with acetylene groups and using the resultant glassy carbon as the stationary phase in a separation process. Glassy carbon with preselected selectivity and retention characteristics can be generated by controlling the temperature of which the glassy carbon is processed.
