| Feature | This phase is recommended for most of applications but particularly effective for basic organic compounds. | This phase is recommended for the separations requiring acidic mobile phase conditions. It also shows superior molecular shape selectivity to monomeric type C18columns. | This phase is designed to offer superior retention of polar compounds and excellent reproducibility in highly aqueous mobile phases, even in 100% aqueous. |
* Optimum pH range of columns based on silica gel is between 2 and 7.5.
Applications
Preparative separation of carbazole using 50 mm I.D. column
Carbazole is extracted from anthracene oil (coal tar) and required high purity because it is often used for analytical applications. Following is the preparative separation of carbazol using a 50 mm I.D. COSMOSIL 15C18-AR-II.
