Control of porous properties in organic polymer monoliths

Many applications of porous materials in areas such as catalysis, adsorption, ion exchange, chromatography, and solid phase synthesis rely on the intimate contact with a surface that supports the active sites.

Monolithic stationary phases

As a new type of chromatographic stationary phase, monoliths have been subjected to intensive study in the last years. They differ from other supports mainly in their characteristic structure, which results in the improved chromatographic properties.

Liquid chromatography modes

Liquid chromatography modes Liquid chromatography offers numerous possibilities how to separate samples of interest. By changing the composition of mobile phase and/or character of stationary phase the separation efficiency and selectivity can be completely change. Read more about main liquid chromatography modes.
