Chromalite MN polymers are hypercrosslinked microporous copolymer with a polystyrene matrix with hydrophobic properties. The proprietary method of production provides a polymer with extremely surface area that makes this product ideal for hydrophobic interaction and adsorption. High bead integrity, excellent chemical and physical stability, very low extractibles content, resistance to changes in chemical conditions,good kinetics and excellent selectivity make these products especially suitable for high purity sorption and chromatographic separations. Chromalite MN polyers are  manufactured to a controlled porosity and particle size specification for efficient chromatographic column packing.
