• Organic Compounds (Low M.W.) Octadecyl group bonded column (C18, ODS) are recommended as first-choice columns for separations of organic compounds (Low M.W.). If there is not enough separation or no retention using COSMOSIL C18 co...

Reversed Phase C18 Series

About Core Shell Particles

Core-shell particles consist of a nonporous core inside a porous shell. By using these core-shell particles, one can achieve sharper peaks compared to fully porous silica gel particles of the same diameter. ...

SFC (Supercritical Fluid Chromatography) Columns

COSMOSIL SFC Column Series

Supercritical Fluid Chromatography (SFC) has become more attractive because it offers some advantages over HPLC, such as high speed, unique selectivity and environmentally friendly separations. Many conventional normal-phase stationary phas...
