Optimum Separation of Polar Non-ionic Organic Compounds
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
