Spectral Pixel-Based Analysis and Clustering Workflow for the Exploration of the Composition of Gas Oil Samples by Comprehensive Two-dimensional Gas Chromatography Vacuum Ultraviolet Spectroscopy.

ABSTRACT: Obtaining an insight into the composition of fuel and process intermediates samples is important for monitoring of the product quality, production and exploitation process improvement and complying with industry and environmental regulations. A broadband vacuum ultraviolet (VUV) spectroscopy detector has been successfully hyphenated with both GC and comprehensive two-dimensional gas chromatography (GC×GC) for the analysis of various fuel samples. This detector possesses both qualitative and quantitative capabilities. Most compounds absorb in the vacuum ultraviolet spectral range, and they exhibit rich and distinctive spectral features. Main constituents of fuel samples, hydrocarbons, such as paraffins, olefins, naphthenes, aromatics are identified with the VUV with very good selectivity. A
