Ultimasyil Amino HPLC Columns (150 Å pore size) are high-performance silica-based columns functionalized with aminopropyl (NH₂) ligands. Designed for versatile use in normal-phase, HILIC, and weak anion-exchange chromatography, these columns are particularly suited for the separation of polar and bio-relevant compounds with larger molecular sizes.
Technical Specifications:
Stationary Phase: Aminopropyl bonded silica
Pore Size: 150 Å – ideal for larger polar molecules
Surface Area: ~170 m²/g
Carbon Load: Approx. 8–10%
pH Range: 2.0 – 8.0
Particle Sizes: 3 µm, 5 µm
Silica Purity: High-purity, fully porous spherical silica
Endcapping: No (for full aminopropyl reactivity)
Key Features:
Dual-mode functionality: operates in HILIC and normal-phase modes
Excellent retention and resolution of carbohydrates, oligosaccharides, and polar organics
Suitable for mass spectrometry detection due to low bleed and clean baselines
Ideal for sugar analysis, nucleotides, and phosphorylated compounds
Enhanced pore size (150 Å) allows better access to larger polar molecules
