"Cogent TYPE-C Silica" HPLC column

Unique "TYPE-C Silica" used in columns for Cogent HPLC manufactured by MicroSolv in the USA.

The "Cogent TYPE-C column," developed by MicroSolv in the United States, is a next-generation HPLC column based on high-purity Type-B silica that has been modified to replace over 95% of the silanol (Si-OH) on the silica surface with silane (Si-H). By replacing over 95% of the silanol with Si-H, a strong hydrophobic surface is created, providing greater stability compared to traditional silica-based phases. This means that end-capping is not necessary. 【Features】 ■ Usable in three modes in HPLC (RP (reverse phase), NP (normal phase), ANP (aqueous normal phase)) ■ High efficiency and high stability ■ Fast equilibration in gradient ■ Simultaneous separation of polar and non-polar compounds ■ Weak hydration shell *For more details, please refer to the catalog.
