Long Column Lifetimes and Excellent Performance

Ultra-pure, metal-free silica (99.99 % purity) is the back-bone of all Luna material. The resulting high quality particles have a surface smoothness, pore structure, and pore consistency to ensure a more uniform particle shape and greater reproducibility.

Wide pH Stability

Luna C18(2) columns are renowned for their exceptional pH stability, offering a wide operational range from pH 1.5 to 9.0. This extended pH range is achieved through the high density of the bonded phase. As a result, peak shapes remain sharp and consistent across varying pH levels, ensuring reliable performance. The wide pH stability of Luna C18 columns allows analysts to work above the pKb of basic compounds, rendering them more hydrophobic. This enhances retention, improves peak shape, and boosts reproducibility, making Luna C18(2) an ideal choice for flexible and long-lasting HPLC methods.

Mobile Phase Compatibility

When using HPLC columns, it’s crucial to use HPLC-grade solvents and materials while avoiding immiscible solvent/buffer combinations to prevent column damage. To ensure the highest performance, solvent filtration is strongly recommended to eliminate trace impurities from your chosen mobile phase.

All Luna HPLC columns, including the widely used Luna C18(2), are stable in 100% organic conditions, offering flexibility in method development. It is essential to keep the mobile phase pH within the recommended limits for each stationary phase to avoid compromising the column’s integrity and lifespan. Adhering to these guidelines ensures optimal column performance, extended longevity, and consistent, reliable results in your chromatographic analyses.

Common Applications on Compounds

Luna C18(2) columns are widely used in various analytical applications due to their versatility and reliability. These columns are particularly effective for the separation and analysis of a broad range of pharmaceutical and bioactive compounds.
