Kromasil 100-10-SIL 20 x 150 mm

The Kromasil 100 SIL HPLC column 150x20mm, 10µm, is based on unmodified silica with 100 Å pore size. The material offers a polar surface, high mechanical stability and a narrow particle size distribution for reproducible normal phase separations. Kromasil 100 SIL can be used for small molecules and peptides when adsorption selectivity or a reference phase without organic modification is required. Typical applications include normal-phase HPLC, method development, isomer separations, purification tasks, pharmaceutical intermediates and the characterisation of polar substance mixtures.

Performance Characteristics and Benefits

• Spherical, fully porous silica with high mechanical stability
• High surface area and high pore volume for efficient separations and good loading capacity
• Narrow particle size distribution for high efficiency and reproducible results
• Broad phase spectrum for reverse-phase, normal-phase, HILIC, and SFC
• Suitable for analytical method development, routine analysis, scale-up, and preparative applications

Additional Information

The Kromasil series is based on highly stable, spherical, and fully porous silica particles. The silica matrix combines a high surface area, high pore volume, and a controlled pore structure with a narrow particle size distribution. This supports efficient packing beds, low pressure drops relative to performance, and good column and batch reproducibility. The Kromasil platform offers different pore sizes: 60 Å for small organic molecules, 100 Å for small molecules and peptides, and 300 Å for proteins and larger biomolecules. Appropriate Kromasil pre-column cartridges can be used to protect the analytical packing bed from particles, sample matrix, and hard-to-elute components.
