C18 / 5 µm / 125 Å
XTerra-packed columns combine the best properties of silica and polymers with the revolutionary patented* Hybrid Particle Technology, which replaces one out of every three silanols with a methyl group during synthesis. This hydrophobicity is distributed through the entire structure of the particle backbone, resulting in a rugged hybrid (inorganic/organic) particle that can be operated at high speeds, high temperatures, and high pH. The presence of 33% fewer residual silanols (after endcapping and bonding) also means that XTerra columns give exceptionally sharp, high-efficiency peaks for basic compounds.
