C18 Gravity Spherical

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.

For Gravity Chromatography Columns

C18 Gravity is available in porosities of 100Å, 300Å, and 500Å and a particle size distribution of 75-200µm.

Quality and Diversity

C18 Gravity is manufactured on Sorbtech’s Premium Rf™ Spherical Silica Gel which boasts narrow pore and particle distributions, ensuring optimal selectivity, capacity, efficiency, low operating pressure, and shorter processing time.

Purity

Premium Rf Spherical Silica Gel is manufactured to a high chemical purity standard (99.9% 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.
