Installed in series in front of Bio-Rad analytical columns, this system offers convenient and highly efficient in-line purification of sugar samples. The system consists of two Micro-Guard cartridges, one packed with anion and the other with cation exchange resin. In-Line Carbohydrate Deashing System protects Aminex® carbohydrate columns from contamination by removing all inorganic salts from the sample, allowing only neutral carbohydrates to pass to the analytical column. Aminex® HPX-42C Column is optimized for analysis of mono- and disaccharides in starch hydrolysates, and provides excellent resolution of oligosaccharides as large as D-10. Aminex® HPX-42A Column, for fast, high-resolution oligosaccharide analysis, separates oligosaccharides to D-11 in approximately 25 minutes. Aminex® HPX-87K Column for the analysis of mono-, di-, and trisaccharides in samples such as corn syrup and brewing wort, exhibits good separations of glucose, maltose, and maltotriose. This column is compatible with salts, so there is no requiement for desalting samples before analysis. The 250×4.0 mm column is appropriate for sugar alcohol separations.Īminex® HPX-87N Column is optimized for the analysis of sugars in samples with high salt concentrations, such as beet sugars. The 300×7.8 mm column is used primarily for the quantitation of glucose and fructose in high fructose corn syrup and for general monosaccharide analysis. Aminex® HPX-87C Column, for most general sweetener analyses, is optimized for analyzing monosaccharides and also provides class separation of di-, tri-, and tetrasaccharides. Research length (300 mm) columns provide high-resolution separations of complex carbohydrate mixtures in approximately 20 minutes, while the shorter columns provide efficient separations of specific carbohydrates in 3 to 5 minutes. Aminex® media have a high pressure stability, wide pH stability, and high column efficiency and selectivity. Usually with minimal sample preparation, just filtering through a 0.45 µm filter with no derivatization necessary. Aminex® Columns allow the use of simple isocratic methods, eluting with water or dilute acid. For oligosaccharides low cross-linked resins allow carbohydrates to penetrate, and oligosaccharides to separate by size. For monosaccharide separations ligand exchange is affected by the nature of the counterion (Pb²⁺, Ca²⁺, etc.) and by the spatial orientation of the carbohydrate's hydroxyl groups. Size exclusion is the primary mechanism for both monosaccharide and oligosaccharide separations. HALO® Chromatography Columns and Consumables+.
