Luna Omega HILIC columns combine thermally modified fully porous particles with a bonded diol stationary phase to provide enhanced retention and selectivity for polar analytes under HILIC conditions. Designed for small polar molecules, metabolites, nucleobases, pharmaceuticals, and other challenging compounds, these columns deliver excellent chromatographic performance and robustness.
The diol stationary phase provides multiple interaction mechanisms that improve retention and separation of polar compounds while maintaining excellent peak shape and reproducibility. The thermally modified fully porous particles extend column lifetime and ensure reliable performance across demanding analytical workflows.

Astounding Performance
The undeniably high efficiency levels found in each Luna Omega UHPLC column provide you with the potential of huge gains in method performance. While traditional silica and hybrid fully porous particles claim high performance, when compared to Luna Omega 1.6 μm, they drastically fall short and prevent UHPLC scientists from reaching their UHPLC potential.
Separation Muscle
Our industry leading bonding technologies in conjunction with high efficiency levels ensure excellent stationary phase coverage and improved separation power. Now, with Luna Omega 1.6 μm, you can turn difficult separations into resolution achievements.
Inert Foundation
Luna Omega UHPLC columns contain a unique silica modified using a proprietary, post-synthetic thermal treatment process to provide extraordinary mechanical strength and significantly greater inertness than traditional fully porous and hybrid materials. This greatly minimizes secondary interactions that negatively affect peak shape, allowing for greater method accuracy.
Consistent Results
Batch-to-batch and column-to-column, Luna® Omega media and columns are designed to be consistent and incredibly accurate tools for your analysis. Each batch and column are quality tested to ensure dependability and reproducibility.
