Long Column Lifetimes and Excellent Performance


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
