詳細

詳細

Preparative HPLC involves much higher sample loading volumes than analytical chromatography. Consequently, greater sample throughput and separation speed are essential for optimal productivity. These criteria are best fulfilled by Chromolith^® Prep RP-18 endcapped columns. The combination of macro and mesopores maximizes separation efficiency and flow rate, while minimizing resistance.

The revolutionary, monolithic silica with its unique combination of macropores and mesopores enables:
—Rapid separations at very low column back-pressure
—High matrix tolerance, allowing time and cost savings with simplified workflows
—Cost savings due to extended column lifetimes
