摘要：

Low angle laser light scattering as a second detector for size exclusion chromatography separation leads to true values of OVER BAR M//w but OVER BAR M//n and molecular weight distribution (MWD) are strongly dependent on axial dispersion sigma and calibration system. Here, we discuss (i) on certain experimental parameters and (ii) on the influence of sigma for two MWD and different calibrations on OVER BAR M//n values and calculated MWD.
