Determining and identifying individual analytes within a complex sample can provide important information to better understand a product or process. This exploratory analysis is readily accomplished with GC-TOFMS, as it provides non-targeted data with every acquisition. The Pegasus BT adds to the chromatographic separation by taking advantage of the full mass range data with mathematical deconvolution to further separate chromatographic coelutions. These capabilities provide excellent information about a sample and the ChromaTOF brand software contains tools to help streamline data analysis.

Petroleum Forensics is the art of tracing the geochemistry of crude oil using petroleum biomarkers. Chemical biomarkers that are resistant to weathering and other forms of degradation ("molecular fossils") are crucial for differentiating the various sources.

Comprehensive two-dimensional gas chromatography can help characterize crude oil by assessing volatile and semi-volatile portions of petroleum samples to isolate and identify chemical biomarkers.

Peak tailing and internal standard reproducibility often make quantitative analysis of polycyclic aromatic hydrocarbons (PAHs) particularly challenging. The addition of a complex matrix only makes experiments even more problematic.

Using a combination of comprehensive two-dimensional gas chromatography (GCxGC) and high performance time-of-flight mass spectrometry (TOFMS) found in the LECO Pegasus BT 4D, PAHs are separated from matrix interferences using both orthogonal column phase selectivity and additional extracted ion mass precision.
