ProntoSIL Enviro-PTL is a special stationary phase for the group determination of non aromatic, monoaromatic, diaromatic and polyaromatic hydrocarbons in petroleum products. This stationary phase was designed to meet the requirements of European Norm prEN 12916 (June 1997). In this procedure a resolution between Cyclohexane (non aromatic) and o-Xylene (mono aromatic) of minimum 7 is required. Therefore the columns packed with this stationary phases are only offered in the length of 250 mm. The columns are pretested with the standard of the application.
