Cosmosil® 3C18-EB

Nacalai Tesque Cosmosil® 3C18-EB Analytical HPLC Column, 3µm, 120Å, 3mm I.D. x 150mm Length, 1/Pk

Product Number: 09814-51

Conventionally end-capped C18 columns still have many residual silanol groups on the silica surface of stationary phase that can form ionic bonds with basic compounds. The resulting peak tailing makes accurate quantification of analytes difficult, especially in trace analyses. COSMOSIL 3C18-EB with a better end-capping treatment offers improved peak shape and separation particularly for basic compounds.

  • Excellent for Basic compounds
  • Improved separation for acidic or metal coordination compounds
  • Simple mobile phase conditions
  • Suitable for drug analysis

Features: 

  • 3C18-EB - This phase with a better end-capping treatment offers improved peak shape and separation particularly for basic compounds.
  • C18-MS-II - This phase is recommended for most applications but particularly effective for basic compounds.
  • C18-AR-II - This phase is recommended for separations requiring acidic mobile phase conditions. It also shows superior molecular shape selectivity to monomeric type C18columns.
  • C18-PAQ - This phase is designed to offer superior retention of polar compounds and excellent reproducibility in highly aqueous mobile phases, even in 100% aqueous.
