Fuel, Petroleum Product and Lubricant Examination

How the Examination Is Conducted

The analysis of petroleum products and lubricants relies on modern methodologies of forensic and analytical chemistry that ensure a high level of accuracy and reliability:

• chromatographic analysis – for determining composition and identifying contaminants or adulterants;

• spectroscopic techniques (IR, UV–Vis, mass spectrometry) – for establishing molecular structure and component profiles;

• physicochemical testing – for evaluating the operational and performance characteristics of fuels and lubricants;

• comparative analysis – matching samples with reference materials to determine conformity or origin.

The integrated use of these analytical approaches makes it possible to detect even minor compositional changes, determine the origin of a substance, and substantiate expert conclusions with high confidence.

Where This Examination Is Used

The forensic examination of petroleum products and lubricants has practical significance across a wide range of applications:

• in criminal investigations – in cases involving fires, arson, traffic accidents, and fuel theft;

• in commercial and civil disputes – when assessing deliveries of substandard fuels or lubricating materials;

• in technical and industrial contexts – when determining the causes of equipment or machinery failure.

The results of such examinations allow investigators and courts to:

• confirm or refute competing versions of events;

• identify non-compliance with product standards;

• provide objective, legally admissible data to judicial authorities.

Forensic fuel and lubricant examination is not only a scientific analysis of composition and properties – it is a reliable evidentiary tool that can play a decisive role in legal proceedings and commercial disputes.
