UOP 649-10 is a UOP method for measuring total oxygen in solid, semi-solid, and high boiling point liquid hydrocarbons by pyrolysis. For laboratories working with heavier or less volatile hydrocarbon materials, this type of test supports a practical understanding of oxygen content in samples that may affect product evaluation, material review, or specification checks. It is a useful reference for teams that need a reliable analytical method for comparing feedstocks, intermediates, or finished hydrocarbon materials where oxygen measurement is relevant to quality control and technical decision-making.

UOP 649-10 method scope

This UOP 649-10 test method is focused on the determination of total oxygen in hydrocarbon materials that are solid, semi-solid, or high boiling point liquids. The title indicates a pyrolysis-based analytical approach, making it a laboratory method for oxygen measurement rather than a general process test. It is best suited to controlled analytical work where the oxygen content of a sample must be evaluated in a reproducible way. That makes it relevant for petroleum testing and chemical laboratory review of heavier hydrocarbon streams and related materials.

Where is UOP 649-10 used?

UOP 649-10 is commonly used in laboratory settings that support refinery QA/QC, petroleum analysis, and technical product review. It may be selected by laboratory analysts, analytical chemists, and quality specialists who need to assess oxygen content in heavier hydrocarbon samples or high boiling materials. The method is also relevant to technical teams comparing material performance, reviewing incoming or outgoing product quality, or documenting analytical data for internal specifications. In practice, it supports organized sample evaluation where oxygen measurement is part of the review process.

Why professionals use UOP 649-10

Professionals use UOP 649-10 when they need a focused, method-based way to evaluate total oxygen in non-volatile or difficult-to-handle hydrocarbon samples. It helps support consistent laboratory reporting, product comparison, and quality verification in environments where small compositional differences can matter. For refinery and laboratory teams, the method can improve clarity in sample interpretation and provide a dependable basis for technical decisions. It is especially valuable when oxygen content must be documented as part of broader petroleum or chemical testing workflows.
