Qualitative and Quantitative Analysis of Polycyclic Aromatic Hydrocarbons in Diesel by GC×GC-FID
Based on the pollution hazards of polycyclic aromatic hydrocarbons,it is necessary to strengthen the determination of polycyclic aromatic hydrocarbons in diesel and strictly control their content.This article uses full two-dimensional gas chromatography hydrogen flame ionization detector(GC×GC-FID)technology(hereinafter referred to as gas phase ion detection)to achieve qualitative and quantitative analysis of polycyclic aromatic hydrocarbons in diesel.After briefly describing the measurement theory of this method,the four group composition of polycyclic aromatic hydrocarbons,including tricyclic+aromatic hydrocarbons,bicyclic aromatic hydrocarbons,monocyclic aromatic hydrocarbons,and non aromatic hydrocarbons,was determined using full two-dimensional gas chromatography-time-of-flight mass spectrometry(GC×GC-TOF MS),and 37 qualitative compounds were identified.Secondly,the peak area normalization method is applied for quantitative and qualitative analysis of polycyclic aromatic hydrocarbons.Finally,discussing the results can effectively qualitatively and quantitatively analyze polycyclic aromatic hydrocarbons in diesel.
