Hamilton Company offers one of the most comprehensive selections of chromatography columns in the industry. Separate Mono and Disaccharides Separate oligomers from DP1 to DP8 Compatible with RI detectors 9 micrometers particle size Multiple column internal diameters available Stainless Steel or PEEK hardware available Buffer strength 0.0 - 0.05NEach column is manufactured under rigorous criteria and tested for resolution and retention time accuracy. This product employs polymeric cross-linked soft-gel materials for cation, ligand exchange separation of carbohydrates. H5 gel-type cation exchange columns are especially useful for determining ethanol in fermentation broths and for separating sugars and sugar alcohols in food samples like com syrup, chewing gum sweeteners, and fruit juices. H5 columns separate compounds through size exclusion and ligand exchange. Ligand exchange dominates in the more highly cross-linked H5.
