Kromasil PHENYL phase bonded to Kromasil silica. Kromasil is manufactured by Nouryon (former AkzoNobel), Sweden. It has been designed for both analytical and preparative scale liquid chromatography applications and is available in six particle sizes ranging from 3.5um to 16 um. A choice of particle size enables the chromatographer to optimize a separation in the most economic manner. Kromasil’s spherical uniform particles have a narrow pore size distribution and a unique surface chemistry. They give high chromatographic performance in both large and small scale applications.
