Developed by Nacalai Tesque in Japan, the Cosmosil line is recognized worldwide for the exceptional quality of its ultra-pure silicas and its unique selectivities.

From conventional HPLC separations to the complex challenges of stereoisomerism or highly polar compounds, Cosmosil offers high-precision stationary phases tailored to the requirements of R&D and quality control laboratories

Cosmosil's flagship product lines and technologies:

  • Ultra-Pure RP Phases (MS-II / AR-II): Deactivated silicas with very low bleed for perfect peak symmetry, ideal for LC-MS coupling.
  • Cosmocore Core-Shell Technology: Solid-core particles for ultra-fast, high-resolution analyses without excessive overpressure.
  • Specialized Selectivities (Promatic & Pi-Pi): Cosmosil Cholester: Superior steric retention for the separation of isomers and structurally similar compounds.
  • Cosmosil PBr & NAP: Pi-Pi and brominated interactions to retain polar compounds without resorting to HILIC phases.
  • HILIC Line: Triazole-functionalized phase for reliable analysis of highly hydrophilic small molecules.
  • Fullerenes & Biopolymers: Dedicated columns (Buckyprep) for the separation of nanostructures and macromolecules.
