Scope: This document describes a method for the determination of total aromatics in jet fuel using gas chromatography. This document is applicable to the determination of the total amount of aromatics in jet fuel with an end boiling point below 300 °C, and the determination range of aromatics mass fraction or volume fraction is 0.5%~35%. Note: The content of olefins in jet fuel is affected by its production process, and the content is relatively low. The capture material used in this document is a reversible selective adsorption material, which selectively adsorbs aromatic components during the analysis process. If the sample contains olefins , olefins and aromatics co-elute, and the determination result of aromatics will be too large. This document is not applicable to the determination of the content of monomeric hydrocarbon components in each hydrocarbon group.
