Therefore, the choice of which method to use depends largely on the nature of the sample elution curve shape and the GPC detector signal-to-noise conditions. In theory, Chevron-2 is also applicable for nonlinear calibration curve by using the local calibration slope of D (v) at every retention volume. Such practice however will add more detector noise effects and more precision problems to the calculations when dealing with real experimental data. 2 What are presented in this paper are two theoretical models of GPC axial dispersion correction.

However, the difference shown is inaccurate because while the M ,i curve from the D V detctor is valid, the M is not. That is, equation 5 rather than equation 6 should have been used to calculate M i, but this would not be feasible for an unknown sample.
