Nouryon - Kromasil

Since October 2018 the famous Kromasil™ chromatographic silica is manufactured by the stand-alone company Nouryon™ in Sweden. The transition occured due to the acquisition of AkzoNobel Specialty Chemicals (former Eka Chemicals™) by The Carlyle Group. The whole manufacturing process is fully automated with multi-kilogram batch sizes ensuring optimum reproducibility.Kromasil chromatography silica is a spherical, totally porous silica-based media and offered within four different Kromasil families: Classic, Eternity, Chiral and SFC. The traditional silica gel Kromasil is now also available with particle sizes 1.7µm and 2.5µm for UHPLC. Kromasil Eternity offers longer column life times and operating in a wider pH-range from 1-12 by modified silica. The Kromasil chromatographic silica is available as bulk material for packing Dynamic-Axial Compression (DAC) Columns.

Additionally prepacked Kromasil analytical, semi-prep and preparative columns can be obtained. The ClassicShell columns are the newest member of the Kromasil family. With 2.5µm solid-core particles the ClassicShell columns are available with C8 and C18 derivatization, in 2.1 and 4.6mm internal diameter HPLC columns.
