Rapid molecular weight analysis of polymers by temperature gradient interaction chromatography
چکیده انگلیسی
Temperature gradient interaction chromatography (TGIC) has been established as a high-resolution technique for the characterization of synthetic polymers. So far, most of the TGIC investigations focused on the high-resolution analysis and little effort has been made on the reduction of the analysis time. In this study, we examined the effect of the column heating rate, the eluent flow rate, and the column length on the TGIC analysis time. We found that the heating rate is the most important experimental parameter to control the TGIC retention time. With a C18 silica column (50 mm × 4.6 mm I.D.), a set of PS standards of wide molecular weight range (5-648 kg/mol) could be separated within 4 min at a heating rate of 8 °C/min.
