Luna Omega HPLC/UHPLC LC Columns
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
