The Kromasil® Classic 100 Å family of products is used to separate and purify molecules of up to 10000 Da. Drug candidates for the pharmaceutical, natural products and API industries are separated and purified using Kromasil® Classic 100 Å columns.

• Spherical porous high purity silica
• Analytical to preparative particle silica: 1,8; 2,5; 3,5; 5; 10; 13 and 16 µm
• 1,8 µm columns suitable for UHPLC conditions; 2,5 µm columns suitable for HPLC and UHPLC conditions
• Unbonded (SIL) and derivatised (C1, C4, C8, C18, C18(w), NH₂ and Phenyl) phases available
• C18(w) is specially engineered for bioseparations and API manufacturing and can be loaded and run under 100%; the phase is ideally suited for polar compound analysis
• Excellent mechanical and chemical stability leading to long column lifetime
• High reproducibility

The narrow and consistent particle size distribution of Kromasil® 100 Å silica and its derivatizations lead to chromatographic columns with outstanding efficiency and bed stability.
