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.

This performance note pertains to all LECO Glow Discharge Spectrometers (GDS). The purpose is to provide recommendations and associated procedures for different sample preparations prior to presenting the sample to the GDS system.
