Obelisc N is a mixed-mode column with very polar characteristics that works well for polar and charged analytes.
- Obelisc N offers both positively and negatively charged groups to interact with positively or negatively charged analytes
- Multiple separation modes available (NP, HILIC, IE)
- In HILIC mode, Obelisc N offers different selectivity form other HILIC or bare silica columns
- LC-MS, ELSD, preparative and low UV (<220 nm) compatible, low concentration buffers
