The Velox C18 is a rugged, general-purpose column for a variety of sample types and mobile phase solvents from pH 2.0 to 8.0. It provides the most hydrophobic retention of any Velox phase and is suitable for the analysis of antibiotics, flavanols, alkyl acids, and many other compounds in food safety, environmental, and pharmaceutical applications. The Velox superficially porous particle (SPP) provides UHPLC-like high speed, high resolution separations to reduce run time and increase sample throughput when run on a standard HPLC system. pH range 2-8, maximum temperature 80C, maximum pressure 400 bar/40 MPa/5800 psi.
