Reversed Phase Chromatography Octadecyl Types

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.

• Features strong acid resistance
• Suitable for acid compounds and peptides

COSMOSIL 5C18-MS-II 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.
