Cosmosil 5C18 AR-II
◈ Product Information
The majority of chromatographers use reversed phase silica-based HPLC columns due to their excellent retention characteristics, high theoretical plate number, good cost-performance and ease of use. C18 or ODS reversed phase columns are the most general and popular types. Monomeric and polymeric types are available differing considerably in their retention characteristics.
Nacalai has been offering the monomeric type COSMOSIL® 5C18-MS and the polymeric type COSMOSIL® 5C18-AR columns, both well received by many chromatographers due to their excellent performance. However, the COSMOSIL® 5C18-AR-II can be used for a wider range of compounds than other polymeric types of columns already in use.
► Point
► Characteristics
The COSMOSIL® 5C18-AR-II packed column features a polymeric and near-perfectly end capped type of C18 reversed phase material that employs an ultra-pure silica gel low in metal impurities. In addition, it has stronger acid resistance than the COSMOSIL® 5C18-AR. The COSMOSIL® 5C18-AR-II column is especially effective for the separation of chelating compounds as well as both acidic and basic compounds.
This series of columns is also highly recommended for a wide range of applications particularly in situations where monomeric-type column (for instance, COSMOSIL® 5C18-MS-II) is not as effective as expected.
► Acid resistance
The acid resistance of COSMOSIL® 5C18-AR-II is much improved compared with 5C18-AR. It retains high performance even in case of acidic mobile phase used to separate proteins and peptides.
