COSMOSIL C18-MS-II HPLC Columns

  • Multi-purpose C18 Column
  • High reproducibility
  • A wide range of applications

The COSMOSIL C18-MS-II is a well-balanced column with better basic performance such as sharper peaks of basic compounds and chelating compounds, large hydrophobic interaction, low analytical pressure, and high theoretical plate number. The COSMOSIL C18-MS-II is first-choice column for reversed phase chromatography.
