Obelisc N is a column which has very polar characteristics and 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 (NP, HILIC, IE).
• In HILIC mode, Obelisc N offers different selectivity form other HILIC or bare silica columns.
• Mass spec, ELSD, preparative and low UV (<220 nm) compatible, low concentration buffers.

Obelisc N columns are available in all standard dimensions
