Chromalite® 15SBG is a high purity premium grade gel strong base anion exchange resin in uniform 15 µm (micron) microbead size which has been designed expressly for chromatographic separations. It has a clear gel structure, showing excellent regeneration efficiency and rinse characteristics. High bead integrity, excellent chemical and physical stability, very low extractables content, resistance to changes in chemical conditions, i:e pH 1-14, good kinetics and excellent selectivity make this product especially suitable for high purity sorption and chromatographic separations. This product is 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.
