Obelisc R

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
Column IDs: 22 mm, 10 mm, 4.6 mm, 3.2 mm, 2.1 mm, 1 mm, 0.5 mm, 0.25 mm
Column Lengths: 250 mm, 150 mm, 100 mm, 50 mm, 25 mm, 10 mm
Particles: 10 um, 5 um
Pores: 100 A
