Kromasil® Silica HPLC Column
5 μm particle size, pore size 60 Å, L × I.D. 100 mm × 3 mm
Kromasil®
Kromasil® premium silica-based HPLC columns and chromatography packings are developed for analytical up to process scale applications. Kromasil has superior mechanical and chemical stability, high available surface area, and a narrow pore size distribution. This results in long lifetime and high loading capacity. In addition the surface properties are excellent, making it possible to run even basic compounds without the use of additives.
Kromasil® Products
The Kromasil product offering comprises a broad range of different phases, both for regular HPLC separations and for chiral separations. Kromasil silica packings are designed to meet the highest demands of HPLC, SFC and SMB, from analytical to process scale.
Kromasil HPLC silica consists of perfectly spherical, totally porous particles. They are produced with a narrow particle size distribution for high efficiency, low pressure-drop and best total economy in chromatographic purifications. The uniqueness of Kromasil high performance spherical silica is the combination of:
