title: [Determination of aromatic hydrocarbon types in diesel oil using high performance liquid chromatography with photodiode array detection].
abstract: When using ASTM D6591 to determine the content of aromatic hydrocarbons in diesel oil, a photodiode array detector (PDAD) was used to monitor the separation of aromatic hydrocarbons. The influence of back flush time B was studied and it was observed the results of di-aromatic hydrocarbons or poly-aromatic hydrocarbons will give errors when the back flush time is more than B +/- 0.2 min. The PDAD can also be used to determine the best cutting time between mono-aromatic hydrocarbons and di-aromatic hydrocarbons, when the separation was not baseline resolved.
