Luna 5 µm Phenyl-Hexyl 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

Engineered for Stability
Luna Phenyl-Hexyl columns provide separations not achievable on C18 or C8 columns; such as increased retention for polar‚ aromatic compounds as well as reversals in analyte elution order. Luna Phenyl-Hexyl columns are a reproducible‚ extremely stable phenyl phase.
