Ultra pure, spherical high performance HPLC phase based on silica gel
Polar, monomeric C18 (Octadecyl) modification, polar endcapping, with 10 % carbon content (~ 50 % endcapping)
Properties
Separation mechanism: Hydrophobic and polar interaction
Key features
C18 A phase with alternative, more polar selectivity, suited for the use with pure aqueous mobile phases, 50 % endcapping and resulting 10 % carbon content, outstanding mechanical and chemical stability, suited for analytical as well as semi preparative and preparative applications
Technical data
C18 A phase based on ultra-pure silica gel (purity > 99 %), metal content < 10 ppm, pH-stability 2 - 8, pore size 100 A, particle size 2 μm, 3 μm, 5 μm, 10 μm (15 μm, 20 – 45 μm on request)
Recommended application areas
polar endcapped C18 phase for water soluble and polar analytes, 100 % aqueous eluents for analysis of very polar compounds, basic pharmaceutical ingredients, water soluble vitamins, catecholamines as well as organic acids.
