On-Line Determination of dn/dc for Size Exclusion Chromatography Coupled with a Light Scattering Detector
Hee Cheong Lee, Taihyun Chang*
The internal standard method, which is widely used in chromatographic techniques, is applied to the size exclusion chromatography for the on-line determination of dn/dc value of the sample. This method is found to provide the dn/dc value with suitable accuracy in determining the absolute molecular weight and the molecular weight distribution of the polymers when a light scattering detector is used.
