Chromolith^® Si - Monolithic Silica HPLC Columns

Chromolith® Si HPLC columns are optimized for normal-phase separations of polar non-ionic organic compounds. In addition, they offer all the benefits of monolithic silica technology: high throughput, extremely long column lifetime, lower matrix sensitivity and added column performance through column coupling. Based on high-purity silica, Chromolith® Si columns minimize the negative effects of trace metals.

Features and Benefits

• Optimum separations of polar non-ionic organic compounds
• High throughput at high flow rates with the best overall column quality
• Possibility of flow gradients
• Added column performance by column coupling
• Rigid monolithic structure for a longer column lifetime
• Lower matrix sensitivity
