Ultimasyil C8 is a reversed-phase prep/analytical HPLC column packed with ultra-high-purity silica (≥ 99.99 % SiO₂), ensuring minimal metallic impurities and exceptional performance.
Key Specifications:
Pore Size: 100 Å – optimal for general-purpose applications
Silica Purity: ≥ 99.99 % – promotes cleaner baselines and improved reproducibility
Particle Shape: Spherical silica particles, fully porous, with end-capping
USP Classification: L7 (C8 bonded phase)
Surface Area: Approximately 310 m²/g
Carbon Load: ~10 %
pH Stability Range: Wide, suitable for method development on acidic, basic, neutral, or even chelating compounds
Due to its slightly less hydrophobic nature compared to C18 stationary phases, Ultimasyil C8 is especially advantageous when dealing with strongly hydrophobic compounds that retain too tightly or when faster elution is desired.
