Obelisc R is a reverse-phase analytical column and can be used in traditional, reversed-phase type applications.

• Due to the presence of ionic groups and a long hydrophobic chain, Obelisc R offers additional retention and tuning that is not available with traditional reversed-phase columns.
• Multiple separation modes (RP, NP, IE).
• Mass spec, ELSD, preparative and low UV (<220 nm) compatible, low concentration buffers.

Obelisc R columns are available in all standard dimensions
