Description
Carbomix phases are composed of spherical, low cross-linking polystyrene/ divinylbenzene (PS/DVB) particles with their surfaces modified with sulfonic acid (-SO3H), followed by chelating of calcium ions (Ca+2) or other metal ions. The PS/DVB support has cross-linking degree of 5%, 8% and 10%. The standard Carbomix packings for analytical applications are 5 µm uniform particles. Carbomix resins of 10 µm and above particle size are manufactured for preparative separation applications. Carbomix resins have been specifically designed for high resolution separation of carbohydrates, organic acids, peptides, and nucleic acids.
Packing
Carbomix Ca-NP resins have been specifically designed for high resolution separation of carbohydrates, organic acids, peptides, and nucleic acids. These novel packing materials are based on low crosslinked polystyrene / divinylbenzene (PS/DVB) particles with the surface modified with sulfonic acid (-SO3H), followed by chelating of calcium ions (Ca+2). Their narrow particle size distribution offers high efficiency and high resolution separations. The low cross-linking generates swelling for the resin in the mobile phase, resulting in reasonable surface area and capacity. Figure 1 is a typical test chromatogram for the separation of carbohydrates by a Carbomix Ca-NP5 column.
