Purolite's Chromalite® SBG and SBM are fine microbeaded ion exchange resins for both analytical and preparative chromatography. They have a narrow particle size distribution which provides superior kinetic properties and low pressure drop in HPLC columns. Sizes available are 10, 30, 50, 100, 150 micron diameter.

Purolite's Chromalite® HGN are hypercrosslinked polymer microbeads with very high surface area and are especially suitable for high purity sorption and chromatographic separations. Sizes available are 5, 10, 15, and 70 micron diameter.

For high pressure liquid chromatography (HPLC), Chromalite® MN highly crosslinked macroporous resins are available in 3, 4, 5, 10 and 15 micron particle size with pore size up to 1200 Å. They provide fast efficient separations along with excellent mechanical stability.
