silica particles
High flow resistance - limits ability to shorten run times
Increased backpressure - limits life of pumps, seals, and column
Reduced throughput - long run times
Bed splitting possible - shortens column life & lessens reproducibility
Onyx (B):
Monolithic porous silica rod
Significantly shorter run times. Cut methods by more than half
Low backpressures. Less stress on system and column
High flow rates due to high porosity
No inlet bed settling. Increased reliability, reproducibility, and lifetime
