| Abstract: | The study shows that the reverse flow method to be sutiable for determination of system-induced zone broadening in TFFF. This broadening effect is dependent on retention volume Vr, but independent on the structure of sample eluting with identical Vr Under proper circumstance, the reverse flow method may be used for estimation of the molecular weight distribution of polymer samples. |
