The constituents in synthetic alkylbenzene samples were analyzed by a comprehensive capillary liquid chromatography (mu-LC)xcapillary gas chromatography (CGC). The mu-LC separates the mixture into aliphatic compounds, monosubstituted alkylbenzenes, multisubstituted alkylbenzenes and binuclear aromatic compounds. Each fraction from a single mu-LC injection is stored in turn in a multiloop interface, and then transferred online into CGC sequentially with large volume in-column splitless injection technique for detailed analysis. No sample discrimination was found with this coupling and injection technique. Both the mu-LC column dimension and transfer speed of fraction from interface to CGC were optimized. Quantitative results and the carbon number distribution of each chemical class are obtained by using the comprehensive mu-LCxCGC with flame ionization detection. The reproducibility of peak area is better than 2% RSD.
