In this work aromatic hydrocarbons were determined under normal phase conditions using a KNAUER AZURA® analytical HPLC plus system with RI detection according to the DIN EN 12916:2016. The instrumental setup and method can be used to determine the content of hydrocarbons in motor diesel fules, which is important for protecting the environment and public health. The standards used for system suitability according to DIN EN 12916:2016 are also part of the calibration used in the IP391(2000)/ASTM D6591 methods but the method settings are slightly divergent.
System calibration standard 1 (SCS 1), 1) cyclohexane, 2) 1-phenyldodecane, 3) 1,2-dimethyl benzene, 4) hexamethyl benzene, 5) naphthalene, 6) dibenzothiophene, 7) 9-methylanthracene
Calibration standard level A, 1) 1,2-dimethyl benzene, 2) fluorene, 3) phenanthrene
