COSMOSIL 5C18-MS-II is a monomeric type of C18 phase. A new endcapping treatment with polar groups for "shield effect" has extended the pH range and significantly improved peak shape for basic compounds. This phase is recommended for most of applications but particularly effective for low molecular weight organic compounds.
Features:
High-purity porous spherical silica
Extended pH range
Improved peak shape for basic compounds
Near-perfect end capping treatment
Analytes: particularly effective for low molecular weight organic compounds.
