UOP 997-13 is a laboratory method for measuring the hydrogen content of hydrocarbons by low-resolution pulsed nuclear magnetic resonance spectrometry. It is designed for technical users who need a practical way to evaluate hydrogen levels in petroleum or hydrocarbon samples without relying on broader, less targeted documentation. For refinery QA/QC teams, laboratory analysts, and technical reviewers, this method helps support sample assessment, product comparison, and routine analytical decision-making. UOP 997-13 is a focused UOP test method that can fit into petroleum testing workflows where hydrogen content is an important quality or characterization parameter.

Purpose of UOP 997-13

The purpose of UOP 997-13 is to provide a standardized analytical approach for determining hydrogen content in hydrocarbons using low-resolution pulsed NMR spectrometry. As an instrumental laboratory method, it supports measurement work where hydrogen content is a relevant property for sample characterization, specification review, or internal comparison. The method is suitable for organizations that need a controlled technical reference for petroleum and chemical analysis. By using UOP 997-13, laboratories can align reporting and evaluation practices around a defined UOP method rather than relying on informal or inconsistent in-house procedures.

Laboratory use of UOP 997-13

UOP 997-13 is commonly relevant in laboratory environments that handle hydrocarbon testing, including refinery laboratories, petroleum QA/QC groups, and analytical chemistry teams. It may be used when hydrogen content needs to be checked as part of routine sample evaluation, method selection, or technical review of hydrocarbon materials. The method can also support process engineers and product quality specialists who depend on laboratory data for comparison and documentation. In practice, it fits workflows where a consistent instrumental method is needed to assess hydrocarbon samples with a clear focus on hydrogen measurement.

Practical importance of UOP 997-13

For day-to-day professional work, UOP 997-13 matters because it gives teams a defined way to evaluate hydrogen content with an instrumental laboratory method. That helps improve consistency across sample sets, supports comparison between materials, and strengthens the technical basis for quality decisions. It is especially useful when laboratories need clear documentation for refinery control, product review, or analytical records. UOP 997-13 can also reduce ambiguity in communication between analysts, engineers, and reviewers by tying results to a recognized UOP test method focused on a specific hydrocarbon property.
