Abstract
Monodisperse polystyrenecodivinylbenzene PSDVB microspheres with binary porous structures were synthesized using a modified seeded polymerization method The microspheres had small pores on the surface and big pores in the middle Using the binary porous PSDVB BPPSD microspheres as packing materials for highperformance liquid chromatography several benzene analogs were effectively separated in a column as short as 75 mm due to the high surface areas of the stationary phase Because of the π–π affinity interaction between BPPSD particles and analytes the separation performance of the BPPSD column was better than commercialized C18 column at the same conditions Compared to column filled with nonporous PSDVB particles the back pressure of BPPSD column could be maintained at especially low level even at high flow rates due to the excellent permeability of the fillers In addition approximate baseline separation of C60 and C70 was also achieved in the 75 mm BPPSD columnThis work is financially supported by the Natural Science Foundation of China 21375069 21404065 21574072 the Natural Science Foundation for Distinguished Young Scientists of Shandong Province JQ201403 the Project of Shandong Province Higher Educational Science and Technology Program J15LC20 the Graduate Education Innovation Project of Shandong Province SDYY14028 the Scientific Research Foundation for the Returned Overseas Chinese Scholars of State Education Ministry 20111568 the Science and Technology Program of Qingdao 1314159jch and the Postdoctoral Scientific Research Foundation of Qingdao
