It is mainly used in normal-phase chromatography. Under strict manufacturing conditions, the high purity of the silica gel is guaranteed, reaching 99.999%. ProntoSIL S offers stationary phases with particle sizes of 3, 5, and 10 μm, and pore sizes of 60, 120, 200, and 300 Å. With an extremely wide range of applications, it is suitable not only for normal-phase chromatography for separating macromolecular substances but also for Size Exclusion Chromatography (SEC).
