An improved method for simultaneous calibration of separation and axial dispersion in SEC/LALLS is presented which partially overcomes restriction imposed in the procedure of He et al. (1982). Both methods are comparatively tested by evaluation of SEC/LALLS experiments with samples from commercial grades of polyisobutylene. On the basis of these findings, the range of applicability and the advantage of the novel procedure are discussed.
