Polymer-based columns for Ligand Exchange Chromatography.

Sugar series columns using dual mode of Ligand Exchange and Size Exclusion Chromatography for specific separation of sugars. Separates mono and di-saccharides by combination of ligand exchange and size exclusion mode Counter ion: Ca2+ (divalent metal ions attached to the packing material separate saccharides from sugar alcohol as these columns retain sugar alcohol strongly.) Only water is required for the analysis (c…

High-Resolution, Strong and Weak Anion-Exchange Columns for the Separation of ProteinsThe ProPac® SAX-10 is a nonporous, strong anion-exchange column (quaternary amine functional group). The ProPac WAX-10 column is a weak anion exchanger (tertiary amine functional group). Both are based on a nonporous core particle that provides pressure stability. A hydrophilic layer prevents unwanted secondary interactions and a grafted anio…

Monolith Ion-Exchange Columns for Superior High-Resolution Analytical and Preparative Protein Separations The ProSwift SCX monolith column line has been expanded to include a new 1 x 50 mm column. As with all ProSwift monoliths, the fast mass transfer allows for fast protein separations. ProSwift monoliths offer excellent separations using fast gradients at low and high flow rates, which improve productivity.ProSwift Monolith…

PhyTip® Columns offer automated, flexible and scalable solution for biomolecule separation.   In addition to columns for affinity purification, nucleic acid purification and gel filtration, PhyNexus have developed PhyTip columns for ion exchange. In traditional ion exchange chromatography, samples, wash buffers and gradient elution buffers pass through packed columns in one direction. The PhyTip column is able to s…

HPLC and FPLC Columns for the Analysis and Purification of Biopolymers.Biopolymers, including peptides, proteins, polynucleotides, and other biodegradable polymers, display a variety of ionic charges and differ in terms of hydrophobicity, size, shape and mass. In addition to these structural (and functional) complexities, an individual biopolymer is typically present at low concentration in samples that contain many similar co…

The new Anion column line from Hamilton is designed to meet the special requirements of anion analysis. The unique design of the highly cross-linked porous packing material and the strong covalent bonded surface chemistry ensure excellent durability and high separation efficiency over the entire column lifetime even under harsh conditions. The columns are designed to be used with carbonate-bicarbonate buffer in any concentrat…
