Puritas SIL

Overview

PURITASTM SIL (spherical ultra pure) phases are based on spherical and totally porous silica gel with metal impurities specified to be less than 10 ppm each for Al, Fe, Ti and Zr. Its manufacturing process under strictly controlled conditions produces a material with reproducible distribution of particle and pore size and surface area. The presence of performance-degrading small pores is avoided.

PURITASTM SIL phases for analytical applications are available in 3μm and 5μm particle sizes.

Nowadays, preparative liquid chromatography is used for the purification of a wide range of high value products. PURITASTM SIL series packing materials for preparative chromatography feature narrow particle size distribution and ultra high silica purity. PURITASTM SIL scale up is guaranteed by using the same production procedure for all grades.
