A polyglycol solution containing different molecular weight PEG components was chosen as test solution. By comparing the results obtained by conventional gel permeation chromatography GPC(water as eluent, sample solution as injected solution)and Eluent-GPC (PEG sample solution as eluent, the concentrated sample solution ,diluted sample solution, water, and sample solution itself as injected solution respectively), the advantage and potential practical usage of Eluent-GPC were discussed.

Key words: GPC, Eluent-GPC, Eluent, Polyglycol solution
