Nacalai Tesque HPLC Column COSMOSIL 15C18-MS-II, 120 Å, 15 μm, 20 x 150 mm

COSMOSIL 5C18-MS-II is a monomeric type of C18 phase. A new end capping 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.
