Latest Generation HPLC Column
Moreover, the mediterranea™ sea18 column has been designed to show an excellent retention of polar compounds in a 100% aqueous environment without the problems of unwanted interactions which inefficiently endcapped conventional packings produce. Packing chemistry based on the new MED technology, “multifunctional endcapping deactivated”, achieves levels of deactivation, resistance to extreme pH values and versatility in its chromatographic applications never reached by conventional or polar-embedded reverse phase packings.The MED technology has been rigorously developed to achieve the maximum reproducibility, with the objective that its chromatographic separations will be, column to column, exactly the same.

An essential condition for obtaining the global-best reverse phase packing is an extremely pure silica. The silica particle, on which the new mediterranea™ sea18 packing is based, is obtained from ultra-pure materials, using rigorously controlled manufacturing processes to ensure that the slightest possibility of contamination is avoided. The mediterranea™ sea18 silica required intensive optimisation of numerous processing factors to achieve a perfectly spherical, rigid and inert particle possessing unusually low metal content. The almost total absence of metals is one of the pillars over which the extraordinary properties of the mediterranea™ sea18 column reside.
Nucleosil is a totally porous silica packing, which is available with a full range of substituents. For its high quality level it has come to be one of the most popular HPLC packings.
There are a great variety of particle sizes, so that practically all the field of chromatography is covered, from ultrarapid columns with packings of 3μm, to preparative scale, with packings of 25-40μm, the same selectivity being always maintained.
The packings of 3, 5, 10μm are characterized by their well adapted distribution of particle sizes, which produces a high efficiency and great stability in the HPLC columns.
The Nucleosil packings are also distinguished by their great stability when subject to extreme values of pH ,being able to work between pH 1 and 9. These values are unreachable by the majority of silica packings.
