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 high speed, high resolution separations to reduce run time and increase sample throughput under UHPLC conditions. pH range 2-8, maximum temperature 80C, maximum pressure 1034 bar/103 MPa/15,000 psi. Note: for maximum lifetime, P.Max of 830 bar/83MPa/12,000 psi is recommended.
