Total petroleum hydrocarbon analysis is a routine technique in many environmental laboratories, with many samples needing to be screened. A simple and reliable method is required that provides the shortest analysis time. Agilent J&W Select Mineral Oil meets this need, with a stabilized nonpolar bonded phase specifically for fast mineral oil analysis. The column is temperature stable up to 375/400°C and provides speedy analyses according to DIN H53 and DIN-EN-ISO 9377-2 methods. Thanks to the temperature stability of Select Mineral Oil, C4-C40 hydrocarbons can be analyzed in less then ten minutes. The high temperature stability of the column permits faster bake-out. Note: For optimal injection performance use the special 4-m retention gap part number CP8015.
