GromSil 120 SEC is a size exclusion chromatography (SEC) column from Dr. Maisch HPLC GmbH, packed with fully porous, high-purity silica featuring a 120 Å pore size and specifically calibrated particle structure. This phase enables separations based primarily on molecular size, making it ideal for the characterization of oligosaccharides, peptides, and synthetic polymers in the lower to medium molecular weight range.
Its well-defined pore system ensures stable retention, minimal secondary interactions, and reproducible molecular weight determination in aqueous or organic eluents.
GromSil 120 SEC from Dr. Maisch HPLC GmbH combines size-based selectivity with reliable column performance — ideal for laboratories conducting precise molecular size analysis in bioanalytical and materials research.
