Luna Omega C18 HPLC Columns
Luna Omega 18 HPLC column is an all-purpose UHPLC column that provides improved performance, excellent retention, and greater inertness than traditional C18 columns on the market
Luna Omega C18 HPLC Columns
First Choice C18 for Hydrophobic Selectivity

Luna Omega C18 is an excellent first choice for chromatographers who are just starting method development or attempting to improve upon existing chromatographic results with other C18s. With its higher performance potential, excellent retention profile, and greater inertness, the Luna Omega C18 was designed to be the new all purpose UHPLC solution for industries all over the world.

  • Compatible with All Analytical HPLC/UHPLC Systems*
  • Fully Scalable Particle Size UHPLC HPLC Preparative
  • Highest Reproducibility and Batch-to-batch Confidence

*Luna Omega analytical columns are compatible with all LC system with standard LC column end-fittings threaded in 10-32. Please contact us at Phenomenex.com/chat for any questions and information about fitting compatibility and any other column internal diameters.
