Luna Omega HPLC/UHPLC LC Columns

Product Information
Brand
World Renowned HPLC Media Reinvented for UHPLC!
Luna Omega high performance HPLC column offers better peak shape, greater separation muscle, and extreme dependability. Luna Omega HPLC columns are available in the following reversed phase selectivities, Omega C18, Omega Polar C18, and Omega PS C18.

World Renowned HPLC Media Reinvented for UHPLC!

The cutting edge thermally modified Luna Omega particle delivers high efficiency, ruggedness, reproducibility, and dependability for a wide range of chromatographic analyses. Luna Omega HPLC and UHPLC columns are built upon more then 20 years of applied knowledge, invention, and customer experience in the manufacture and packing of LC columns. The particle’s novel design and proprietary manufacturing process results in greater particle inertness, a stronger particle morphology, and more consistent porosity.

  • Greater separation muscle and retention
  • Consistent porous structure and elimination of micropores
  • Extreme ruggedness and reproducibility
