Biochromatography - Size Exclusion Chromatography

The chromatographic separation of biomolecules based on their size in solution is known as Size Exclusion Chromatography (SEC).

Unlike other modes of chromatography, it relies on the absence of any interaction between the analyte and the stationary phase packed in the column. This provides an ideal solution for separating and analysing intact proteins from contaminants that can include aggregates, excipients, cell debris, and other impurities arising from degradation. SEC is therefore widely used in both development and manufacture for biotherapeutic molecule characterisation.

In this section we provide some key literature to assist you with Size Exclusion Chromatography analysis and application development for a wide range of analyte types.
