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.

This instalment of Tips & Tricks discusses the effect of column order on separation efficiency.

What experimental details need to be considered when analyzing PEGs?

The benefits of a molar mass distribution over molar mass averages and the differences between the different representations of molar mass distributions are discussed.

This instalment of Tips & Tricks focuses on whether a complete separation can be achieved using GPC/SEC and, if so, under what conditions.
