Xtimate Hybrid Series
Xtimate® is a new premium HPLC column series and is the product of several years of continuous research on advanced surface modification at Welch Materials, Inc. The Xtimate Series includes columns based on hybrid silica-polymer packing materials and those based on pure polymer media, as well as size exclusion (SEC) columns.
Hybrid Silica Columns
The hybrid particles based Xtimate® phases are bonded using our improved bonding process. Surface bonding coverage for hybrid particles uses a new organic silane with a more reactive group for bonding and endcapping.
Xtimate® polymer-based columns are based on polystyrene-divinylbenzene (PS-DVB), and can be applied for analysis of organic acids, mixed alcohols and sugar products.
Xtimate® SEC is made from ultra high purity (UHP) stable hybrid silica with UHP hydrophilic polymer and diol functional groups. Our process greatly reduces nonspecific adsorption of polymer, protein, peptide, antibodies and other biologics.
