Carbo Sep Coregel-87MM Guard Kit, SS/pktit 24 mm x 4.0 mm

CarboSep Coregel-87MM guard column cartridges 24x4.0mm, 8µm, are used for column protection in CarboSep Coregel-87MM HPLC columns are used. The matching AXC-99-1300 direct holder is used as the pre-column holder. CarboSep pre-column cartridges protect ligand-exchange columns used in sugar analysis from particles, matrix contaminants and highly retained impurities. The cartridge should be selected to match the counterion, particle size and degree of cross-linking of the relevant CarboSep analytical column.

Features and Benefits

• Polymer-based ligand-exchange resins for carbohydrates
• Various counterions, such as Na+, Ca2+, Pb2+, and K+, for targeted selectivity
• Cross-linking degrees of 4, 6, 7, and 8% to adjust porosity, resolution, and robustness
• Suitable for monosaccharides, disaccharides, and oligosaccharides

Additional Notes

The CarboSep series uses polymer-based packing materials with defined counterions and degrees of cross-linking. Unlike conventional silica phases, retention is not based on hydrophobic surface interactions, but rather on ligand exchange and size- or structure-dependent interactions between the carbohydrates and the polymer resin. This allows sugars, sugar alcohols, and oligosaccharides to be separated in highly aqueous eluents. The polymer backbone used is designed for routine applications in carbohydrate analysis; compatible CarboSep pre-column cartridges help keep matrix components out of the main column.
