HC-75 (H+), 9 æm Bulk Resin

Polymeric 7.5% cross-linked soft-gel columns for cation, ligand exchange separations of carbohydrates. Compatible with UV and RI detectors Hydrogen form columns for USP L17 applications Calcium form columns for USP L19 applications Lead form columns for USP L34 applications One particle size: 9 μm Three column internal diameters: 4.1, 7.8 and 10.0 mm One column material: 316 stainless steel Three forms: calcium, lead and hydrogen Separate compounds through ligand exchange.  HC-75 columns separate compounds through ligand exchange. The 8% cross-linked HC-75 uses ligand exchange as the primary mechanism of separation. The different forms of the HC-75 (Hydrogen, Calcium and Lead) each provide a unique selectivity for separating varying types of charged analytes based on electronegativity toward the counterion. The higher carbohydrate oligomers elute first while the smaller di- and monosaccharaides elute later. Pack Your Own Columns - Hamilton offers a range of bulk polymer resins for customers who prefer to pack their own column hardware. Chromatographic capacity and efficiency tests are conducted on both bulk and packed column resins to ensure product integrity. Samples from different lots can be purchased for method and process validation. Protect Your Investment - Hamilton guard columns protect analytical, semi-prep and preparative HPLC columns. They also remove particulate contaminants and highly adsorptive compounds from samples, prolonging column life. The designs are modular and cartridge replacement is easy and tool-free.  Cartridge holders for analytical columns are available in stainless steel and PEEK materials. Semi-prep/preparative holders are available only in stainless steel. The design of the cartridge holders is optimized to reduce dead volume and prevent extra column band broadening. Cartridge holders are reusable indefinitely.
