COSMOSIL® πMAX - Pyrenylethyl
Stronger π-π interactions than phenyl columns.
Supercritical Fluid Chromatography (SFC) has become more attractive because it offers some advantages over HPLC, such as high speed, unique selectivity and environmentally friendly separations. Many conventional normal-phase stationary phases, such as diol, amino and cyano, have been used for SFC applications. However, these phases present limitations for separations. COSMOSIL SFC Columns have been developed to enhance the capability of SFC separations.
Features:
- Three categories (I–III) of stationary phase for different types of compounds
- Different selectivity from HPLC
Columns for SFC-specific separations
In supercritical fluid chromatography (SFC), secondary interactions such as π-π and dispersion force are stronger compared to high-performance liquid chromatography (HPLC). As a result, these columns are capable of unique separations in SFC.
