验证了逆转法在场流分级这种单相色谱中的可行性。用逆转法消除样品的多分散性对塔板高度的贡献,以便研究在热场流分级柱槽中其它实验条件的影响。测定了几种聚苯乙烯样品的分子量分布。
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.
