Ascentis® Express OH5, 2 μm UHPLC Column
基本信息
| NACRES | SB.52 |
| General description【一般描述】 | The Ascentis® Express 2μm OH5 stationary phase is a highly polar ligand that possesses 5 hydroxyl groups tethered to the silica via novel proprietary linkage chemistry. This high performance material provides a UHPLC column that can be used for traditional normal phase separations using non-polar, totally organic mobile phases or for aqueous normal phase chromatography with the typical mobile phases for hydrophilic interactive liquid chromatography (HILIC) of basic, acidic, zwitterionic, or neutral compounds. |
