The separation of polystyrene standards with molecular weight ranging from 2,900 to 7,450,000 by the HPLC using monolithic silica capillaries with a dimension of 200 μm i.d. × 150 cm was investigated. Monolithic silica capillary columns were prepared by hydrolysis and polycondensation of alkoxysilanes in a fused-silica capillary. The polystyrene was dissolved at a concentration of 5g/L in the mobile phase containing a small amount of toluene and for each measurement, 100nL of the solution was injected into each column. The retention time was determined from the peak maximum and converted to the retention volume at a flow rate. Results show that the separation of polymers in the external pore zone of monolithic silica made in capillary (S-B) was more effective than that made as rod (S-A), and as effective as the separation in the internal pore zone.
