Optimum Separation of Polar Non-ionic Organic Compounds

Chromolith® Si HPLC columnsChromolith® 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
