GromSil phases are characterized not only by their high chemical selectivity, but also by their excellent physical properties: They are absolutely spherical, completely porous and have a high specific surface area. Therefore, GromSil-packed columns exhibit excellent flow properties (e.g. low back pressure), high efficiency (i.e. high plate count) and remarkable peak symmetry.
Dr. Maisch is a manufacturer of the validated Gromsil phases of high quality. In 2015, Dr. Maisch acquired the company Grom-Analytik from Grace Alltech: Grom was a German HPLC column packer known for its excellent capillary columns and amino acid HPLC kits. We offer columns from the GromSil, Grom Saphir, HyperGrom and SpheriGrom series.
The Grom columns continue to use the original Grace packing material.
