LiChrospher® Si 60 and Si 100 are versatile HPLC sorbents that offer optimal polar properties for normal-phase separations. They are based on spherical silica particles with a pore diameter of 60 Å or 100 Å, and a particle size of 5 µm or 10 µm. LiChrospher® Si 60 and Si 100 sorbents are packed into Hibar® RT columns or LiChroCART® HPLC cartridge columns.
