Branching revealed: Characterizing molecular structure in synthetic polymers by multi-angle light scattering
3 Feb 2025This note provides a brief overview of basic principles of the detection and characterization of branching by means of multi-angle light scattering (MALS) detector. The most common methods that can provide branching information are presented and elucidated by means of real experimental results obtained with Wyatt Technology instruments.

Size Exclusion ChromatographySize exclusion chromatography (SEC) is a liquid chromatographic technique used to separate and identify molecules based on their size, including polymers, proteins, nanoparticles & nucleic acid. SEC is further subdivided into gel filtration chromatography (GFC) and gel permeation chromatography (GPC) when an aqueous or organic mobile phase is used respectively. HPLC-based SEC systems and columns are available for analytical separation alongside SEC spin columns or filters to prep samples for many protocols.

Natural polymers such as DNA and proteins are essential to life, whereas synthetic polymers such as polystyrene and polyethylene are used widely due to their functionality. Typical techniques for analysis include GPC, SEC, DSC, FT-IR and NMR.
