How do you judge the potential success of separating two polymers using GPC/SEC?
Determining a theoretical number of plates is an effective tool to ensure that the column is still applicable for the desired separation.
Determination of molar mass distributions and the molar mass averages derived therefrom are the main objectives of gel permeation chromatography/size-exclusion chromatography (GPC/SEC) analysis. But what is the meaning of these averages and how are they influenced by the setting of baselines and integration limits? This instalment of Tips and Tricks in GPC/SEC will try to provide a better understanding.
This installment of Tips & Tricks will provide some helpful pointers to keep your GPC/SEC system in good shape.
