Macrosphere 100 Si is a high-purity silica-based stationary phase designed for organic gel permeation chromatography (GPC). Featuring a 100 Å pore size, this material enables precise size-based fractionation of polymers, oligomers, and other organic macromolecules in non-aqueous solvent systems.
The unmodified silica surface ensures genuine size-exclusion behavior, eliminating secondary interactions and providing highly reproducible molecular weight determinations. Its optimized pore structure allows efficient mass transfer and sharp peak profiles across a broad range of molecular sizes. The phase delivers reliable calibration performance and stable retention even after extensive use with organic eluents. With its mechanically robust silica backbone and excellent chemical resistance, Macrosphere 100 Si is ideally suited for polymer characterization, resin analysis, and quality control in both research and industrial laboratories.
Macrosphere 100 Si combines optimized pore architecture with robust silica stability – the dependable choice for accurate and reproducible organic GPC separations of polymers and macromolecules.
