UOP 866-86 is a laboratory test method for the determination of carbon, hydrogen, and nitrogen by oxidative pyrolysis. For buyers reviewing petroleum and chemical analysis methods, it provides a clear framework for elemental characterization of samples where these three components matter to product understanding, quality review, or technical documentation. The method title points to a focused analytical purpose, making it relevant for organizations that need reliable composition data for process materials, fuels, intermediates, or other laboratory samples. UOP 866-86 is a practical reference for teams that compare results, document composition, or support routine analytical decision-making.

UOP 866-86 method scope

The scope of UOP 866-86 centers on measuring carbon, hydrogen, and nitrogen using oxidative pyrolysis as the analytical approach. In practical terms, this is an elemental analysis method designed to help laboratories evaluate sample composition in a controlled, repeatable way. It is suited to technical work where carbon, hydrogen, and nitrogen values are needed for material review, quality assessment, or method-based documentation. As a UOP method, it fits within petroleum and chemical laboratory workflows that rely on standardized procedures for comparing samples and supporting consistent reporting.

Where is UOP 866-86 used?

UOP 866-86 is commonly used in laboratory settings supporting refinery QA/QC, petrochemical analysis, and technical sample review. It may be relevant to laboratory analysts, analytical chemists, refinery quality teams, and technical reviewers who need elemental data for petroleum-related or chemical materials. Because the method addresses carbon, hydrogen, and nitrogen, it can support routine characterization work, product comparison, and internal documentation where composition data informs next-step decisions. It is especially useful in organizations that depend on standardized test methods for consistent laboratory workflows.

Why professionals use UOP 866-86

Professionals use UOP 866-86 because elemental measurement of carbon, hydrogen, and nitrogen helps create a clearer picture of sample composition. That clarity supports quality control, product evaluation, and technical review when teams need dependable analytical documentation. For refinery and laboratory users, a standardized UOP method can improve consistency across testing programs and make results easier to compare within internal reports or specification checks. It is a practical choice when the goal is to support decision-making with a focused, recognized laboratory method rather than an informal or ad hoc approach.
