Chromalite AD1 are  low porous, non functionalised  highly crosslinked polymers in very small and uniform particle size. Chromalite AD1 products are ideal for high pressure reverse phase liquid chromatography (RP-HPLC).  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 adsorption and chromatographic separations. This series of products are manufactured to a controlled particle size specification for efficient chromatographic column packing. The spherical beads show exceptional batch to batch consistency to enable scale up from laboratory tests, through pilot plant to full plant operation.
