COSMOSIL 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 C18-MS-II, C18-AR-II and C18-PAQ, each of which has a different separation property.
