HPLC chromatography column 10BE081E2F

Ultra pure, spherical high performance HPLC phase based on silica gel Monomeric C8 (Octyl) modification, standard endcapping, with 10 % carbon content (~ 50 % endcapping) Properties Separation mechanism: Hydrophobic interaction (lower compared to C18 phases) Key features Classical C8 phase, standard 50 % endcapping and 10 % carbon load, outstanding mechanical and chemical stability, suited for analytical as well as semi preparative and preparative applications Recommended application areas Similar selectivity to C18 phase but less retention due to the lower hydrophobicity; useful for determination of water soluble vitamins, steroids, catecholamines, sedatives etc. TECHNICAL DATA Separation column Special characteristics - endcapped (ca. 50% standard endcapping) Particle size - 2 µm Pore size - 100 Å Particle shape - spherical, totally porous USP code - L7 Length [mm] - 100 mm Inner diameter [mm] - 2 mm Hardware type - Standard Connection - 1/16" Application area - HPLC Pore volume - 0.8 ml/g Metal content - < 10 ppm Carbon load - 10% Recommended pH range - 2-8 Density - 430 g/l Pressure rating - max. 1000 bar Temperature range - up to 40°C (up to 50 °C short term) Specific surface area - 320 ± 20 m²/g
