Luna 3 µm Silica (2) 100 Å, LC Column 30 x 4.6 mm, Ea
Бренд: Phenomenex
Long Column Lifetimes and Excellent Performance
Ultra-pure, metal-free silica (99.99% purity) is the backbone 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.
Superior Particle Smoothness
Agilent Technologies® ZORBAX® 5 µm SB-C18
Waters® Symmetry® 5 µm C18
Phenomenex Luna 5 µm C18
Either bonded or unbonded‚ Luna silica produces highly advanced HPLC columns:
- Low percentage of «fines» from damaged silica leading to lower backpressures and enhanced column performance and lifetimes
- High column bed stability enhanced by particle shape uniformity
