Reversed Phase Chromatography Octadecyl Types

Standard Reversed Phase Columns

The reversed phase HPLC column is most commonly used because of the high theoretical plate number, excellent separation characteristics, reproducibility, affordable cost and ease of use. Columns packed with the octadecyl group bonded type silica gel (C18, ODS) are the most widely employed. We offer three types of octadecyl group bonded columns: COSMOSIL 3C18-EB, C18-MS-II, C18-AR-II and C18-PAQ, each of which has a different separation property.

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

Separation Property

The COSMOSIL 5C18-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 5C18-MS-II is first-choice column for reversed phase chromatography.
