UOP 971-00 is a laboratory test method for trace nitrogen in light aromatic hydrocarbons by chemiluminescence, giving buyers a focused way to evaluate low-level nitrogen content in these materials. For refinery and petrochemical operations, this kind of measurement can support product qualification, feedstock review, and routine quality checks where nitrogen control matters. As a technical document, UOP 971-00 is most relevant to teams that need a clear analytical reference for comparing samples and documenting results in a consistent laboratory workflow.

UOP 971-00 method scope

The UOP 971-00 method scope centers on the determination of trace nitrogen in light aromatic hydrocarbons using chemiluminescence as the analytical approach. It is intended for laboratory evaluation of samples where very low nitrogen levels may need to be measured with attention to analytical consistency. This makes the method suitable for organizations that need a defined test method for sample review, specification support, or internal comparison work. As a UOP Test Method, it fits technical environments that rely on documented, repeatable chemical analysis.

Where is UOP 971-00 used?

UOP 971-00 is commonly used in petroleum, refinery, and chemical laboratory settings where light aromatic hydrocarbon streams are evaluated for trace nitrogen. It may be relevant to laboratory analysts, analytical chemists, refinery QA/QC teams, and technical reviewers who need dependable test documentation for sample assessment. In practice, the method supports laboratory workflows tied to product quality verification, feed or process sample review, and technical data comparison. It is especially useful when nitrogen content must be tracked as part of broader material characterization work.

Why professionals use UOP 971-00

Professionals use UOP 971-00 because trace nitrogen results can help support quality control, product comparison, and technical decision-making in refinery and laboratory work. A defined method improves consistency across sample evaluations and helps teams communicate results with clearer analytical context. For operations and laboratory personnel, this can reduce ambiguity when reviewing materials, checking conformance to internal targets, or documenting findings for follow-up review. UOP 971-00 is therefore a practical reference for teams that need reliable trace analysis in light aromatic hydrocarbons.
