Meeting the Requirements of EN12916:2006 (IP391/07) Using Agilent 1200 Series HPLC Systems

Abstract: The performance of diesel fuel is predominantly determined by its ignition quality, the Cetane number. Generally, in order to provide the best performance and lifetime of an engine, the amount of aromatics in diesel should be as low as possible. For the analysis of nonaromatics and aromatics in diesel fuel and petroleum distillates boiling in the range 150 ºC to 400 ºC, there exists an IP Method revision (IP391/07), which uses normal phase HPLC with refractive index detection. Recent growth in biodiesel production created a demand for analysis of petrodiesel and petrodiesel/biodiesel blends. In this method revision, fatty acid methyl esters (FAME) originating from biodiesel sources must elute after a tetra-aromatic marker peak, chrysene, which facilitates improved accuracy of large PAH molecules without interference from FAME. The refractive index detector is used because it responds to both non-aromatic and aromatic hydrocarbons.
