This instalment describes the interplay between column length, pore size distribution, and particle size to optimize GPC/SEC separations.

Hydrolyzed collagens (collagen peptides) are water-soluble products obtained by hydrolysis of natural proteins and used for dietary supplements. A simple GPC/SEC method is described for molar mass determination of collagen peptides, allowing reliable molar mass determination using ultraviolet (UV) detection.

How to create a calibration curve when no chemically-matching reference materials with narrow molar mass distribution are available.

A review of alternative approaches to narrow standard calibration.
