Luna Silica(2) HPLC Columns

The Luna® brand of columns and media is more than just a product line from Phenomenex. It is a pledge to provide you with the highest level of satisfaction for your chromatographic goals. Ultra-pure silica with high column bed stability enhanced by particle shape uniformity.

  • Extensive line of rugged particle sizes
  • Easy method scalability from HPLC to preparative and bulk purification LC
  • Ultra-pure, metal-free silica (99.99 % purity) (USP: L3)

Surface Area (m²/g)
400
Particle Size
3, 5, 10, 15
Recommended Use
Ultra-pure, metal-free silica particle that offers great polar selectivity.

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
