C18 HPLC Semi-Prep
C18 silica gel is the most popular and versatile Reversed Phase, capable of hydrophobic interactions with a wide variety of organic compounds.
C18 silica gel is used for Reversed Phase chromatography for the separation of nonpolar to moderately polar compounds such as: Fatty acids, glycerides, Polycyclic aromatics, Esters (Phthalates), Fat-soluble vitamins, Steroids, Prostaglandins, and PTH amino acids.
Other recommended applications: Catecholamines, drugs, drug metabolites, dyes, pesticides, PCBs, antiarrhythmics.

Purity
Premium Rf Spherical Silica Gel is manufactured to a high chemical purity standard (99.95% SiO2). Organics and trace metals content are controlled within stringent limits. Each production batch has undergone extensive quality control testing to ensure reliable lot-to-lot performance. This rigid control of chemical purity, surface area and pore size, ensure our silica will yield reproducible separation results and allow for direct scale-up without requiring time-consuming method redevelopment.
Robust
Our spherical silicas are mechanically robust and can, therefore, be repacked multiple times in either analytical or preparative scale columns.
