GromSil 100 is a group of fully porous silica-based HPLC columns from Dr. Maisch HPLC GmbH, designed for analytical separations of small to medium-sized molecules. Built on high-purity silica with a 100 Å pore size, this platform delivers high mechanical stability, excellent surface homogeneity, and narrow particle size distributions. Various bonded chemistries—including C18, C8, Phenyl, CN, and amino phases—make the group highly flexible for reversed-phase, normal-phase, and polar retention applications.
Each phase within this group supports sharp peak shapes, high efficiency, and batch-to-batch reproducibility—making it ideal for QC, pharmaceutical development, and academic research.
The GromSil 100 group from Dr. Maisch HPLC GmbH combines robustness with proven performance — a reliable platform for high-resolution HPLC across a broad range of compound classes.
