Purospher® STAR Silica and Amino Phases
Purospher® STAR HPLC columns based on high-purity silica are also available for normal-phase separations, and as amino-bonded phases. The benefits of these columns include excellent separation efficiency, and the absence of metallic impurities, resulting in consistently symmetrical peaks.
Purospher® STAR Si (Silica) offers the highest separation efficiency for normal-phase chromatography of low molecular weight compounds soluble in organic solvents.
Purospher® STAR NH2 (Amino) is primarily designed for carbohydrate analysis, with a typical mobile phase consisting of acetonitrile and water. Purospher® STAR NH2 is also suitable for use in the normal-phase retention mode.
