GromSil 80 is a group of high-purity, fully porous silica-based HPLC columns from Dr. Maisch HPLC GmbH, featuring a pore size of 80 Å. This platform is engineered for the separation of small to moderately sized molecules, providing an excellent balance between surface area and mass transfer characteristics. The group includes a range of bonded phases such as C18, C8, CN, and NH₂, enabling broad applicability in reversed-phase, normal-phase, and polar retention modes.
With high column efficiency and robust mechanical stability, these columns are suited for routine analysis, method development, and quality control.
The GromSil 80 group from Dr. Maisch HPLC GmbH offers dependable and efficient HPLC performance — a solid choice for small-molecule separations across a variety of chromatographic modes.
