Cogent HPLC Columns
Manufactured to quality standards meeting the most stringent demands required in separation sciences. Columns you can rely on.
Cogent TYPE-C™ Silica Columns - Premium Innovative Stationary Phases designed for routine and difficult chromatographic applications. Excellent for new method research and development analyses and problem separations such as hard to resolve compounds. Invented and developed by a team of Scientists, Marketing Professionals and Customers; Cogent TYPE-C™ HPLC products are manufactured with state-of-the-art manufacturing technologies. A monolayer of Silica Hydride (Si-H) is built over Type-B, (Si-OH), high purity silica. This Hydride layer covers the silica surface and pores replacing 97% of the surface silanols. This unique surface in conjunction with our proprietary bonding technology results in exciting phases: BidentateC18™, BidentateC8™, Amide™, Diol™, Phenyl™, UDA™ and Cholesterol™. Each phase has a unique character and benefits that are useful in Reversed Phase, Normal Phase or Aqueous Normal Phase. Excellent for LCMS..
