| Product Name | 1.7-50 µm Normal-Phase Silica and Diol Media with 100-1000 Å Pores |
| Catalog No. | IGM-HMM-0298 |
| Description | Alta DiagnoTech normal-phase chromatography media use monodisperse porous high-purity silica. Unbonded silanol and bonded diol options provide complementary selectivity, easy packing, high efficiency, low backpressure and strong mechanical performance. |
| Intended Use | Analytical and industrial separation of organic small molecules, fat-soluble vitamins, tocopherols, natural products, biomacromolecules and other polar compounds. |
| Principle / Technology | Normal-phase liquid chromatography on unbonded silica or diol-bonded silica. |
| Performance Range / Specifications | Particle sizes span 1.7-50 µm. Pore sizes are 100, 120, 200, 300, 500 or 1000 Å, surface area is approximately 30-450 m²/g, bulk density is approximately 0.40-0.50 g/mL, and the pH range is 2-8. Diol phases have approximately 3-8% carbon content. |
