UOP 981-14 is a laboratory method for measuring trace nitrogen in liquid hydrocarbons by oxidative combustion with chemiluminescence detection. It is designed for buyers who need a controlled analytical reference for evaluating very low nitrogen levels in petroleum and related hydrocarbon streams. For refinery and petrochemical laboratories, this type of method helps support sample assessment, product comparison, and quality verification where nitrogen content can affect processing behavior, catalyst performance, or downstream specifications. UOP 981-14 is a practical choice for teams that need a clear, standards-based approach to trace nitrogen analysis.

Purpose of UOP 981-14

The purpose of UOP 981-14 is to provide a formal test method for the determination of trace nitrogen in liquid hydrocarbons using an instrumental analytical approach. By focusing on oxidative combustion with chemiluminescence detection, the method addresses laboratory measurement of nitrogen at low levels in hydrocarbon samples. This makes it relevant when precise analytical documentation is needed for petroleum testing, feedstock review, or product evaluation. As a UOP test method, it supports consistent interpretation of trace nitrogen results across laboratory workflows.

Laboratory use of UOP 981-14

UOP 981-14 is commonly used in laboratory settings that handle liquid hydrocarbon analysis, including refinery quality control, fuel testing, and petrochemical sample evaluation. Laboratory analysts, analytical chemists, and technical reviewers may use it when checking nitrogen content in streams that need close control or comparison against internal targets. It is also relevant for teams reviewing incoming materials, process samples, or finished products where trace nitrogen data supports technical decisions. In practice, the method fits workflows that depend on dependable laboratory documentation and repeatable measurement.

Practical importance of UOP 981-14

For day-to-day professional use, UOP 981-14 matters because trace nitrogen results can influence product qualification, process monitoring, and quality comparisons. A consistent analytical method helps reduce ambiguity when different samples or batches must be reviewed under the same laboratory framework. For refinery QA/QC teams and technical specialists, this supports clearer decision-making and better alignment between reported data and operational needs. UOP 981-14 is therefore valuable wherever trace nitrogen control is part of routine petroleum or hydrocarbon testing.
