What is Size Exclusion Chromatography (SEC)?
Explore the basic principles behind Size Exclusion Chromatography (SEC), including both aqueous SEC/Gel Filtration Chromatography (GFC) for biomolecules and non-aqueous SEC/Gel Permeation Chromatography (GPC) for polymers. This overview highlights how SEC separates molecules based on size, why it’s widely used for protein and polymer characterization, and how different column chemistries support a variety of analytical workflows.
Whether you're working with biomolecules, synthetic polymers, or complex mixtures, understanding SEC fundamentals can help you choose the right column, optimize resolution, and improve overall analytical performance.
