Abstract
This paper describes the development of a quantitative analytical method for aromatics in diesel fuels by capillary multi dimension GC-FID. Methylsilicone and SP2380 were selected for the precolumn and main column, liquid phases to separate the aromatic hydrocarbons from the paraffin hydrocarbons. Separation of hydrocarbons was recognized by GC/MS with an open split interface. From the analytical result measured by this method, it is concluded that aromatics can be separated from paraffins, furthermore, aromatics can be separated according to ring number. The analytical result shows the ratio of aromatics indicated in weight percentage using FID as a detector. The relationship of aromatics analyzed by the FIA method and SFC method showed good correlation respectively.
