High performance spherical silica for analytical to process-scale liquid chromatography.(HPLC). Totally porous silica in 10 µm particle size and 100 pore size. Functionalized with a monofunctional octadecyl silane and end-capped. Available in bulk and in slurry-packed stainless steel columns. Particle Shape Spherical Array C18 Family / Formats HS�® (Functionalized Silicas) Particle Size 40 - 63 �µm / 230 - 400 mesh Pore Size 60 �? Storage Condition Keep dry Silica gel C8-reversed phase was used in the purification of tertiary sulphonamide using FSPE. Pressure induced C8 reversed phase silica gel was synthesized through a sol-gel templating technique.
