Gel chromatography (size exclusion chromatography, SEC) separates molecules by size via a porous gel matrix, with macromolecules eluting first. It includes gel permeation chromatography (GPC) for polymers in organic solvents and gel filtration chromatography (GFC) for biomolecules in aqueous solutions. The ELITE GPC system provides accurate molecular weight distribution analysis with a wide range, short cycles, full software control, and ease of use.

The ELITE gel chromatography system is designed for molecular weight distribution analysis of macromolecules and polymers, featuring a broad measurement range, rapid analysis, and high precision. Its fully software-controlled operation ensures user-friendly performance, meeting diverse molecular weight testing requirements. For example, under the specified chromatographic conditions, calibration curves are prepared using standard samples to analyze the molecular weight distribution of polystyrene.
