| 中文摘要 | the instrumental spreading of a high temperature gel permeation chromatograph (gpc) was evaluated by coupling with a two-angle laser light scattering (talls) detector, using narrow polystyrene, polyethylene, and syndiotactic polypropylene samples. the determined spreading factor increased with increasing molecular weight of polymers, and no maximum for spreading 174 tor was observed in the studied retention volume, while the spreading factors for single low molecular weight alkanes are independent of their molecular weight. neglecting of the spreading effect for gpc would not introduce much error in molecular weight calculation when high quality high performance columns were used, especially when equipped with a laser light scattering detector. the scaling relationship between radius of gyration and molecular weight of polymer, determined by gpc with a talls detector, was independent of the instrumental spreading. |
