UOP 938-20

UOP 938-20 is a laboratory test method for measuring total mercury and mercury species in liquid hydrocarbons, helping professionals evaluate trace contamination and speciation in petroleum-based samples. For buyers comparing analytical standards, it is relevant wherever mercury control affects product quality, handling, or downstream processing. This method supports refinery and laboratory decision-making by providing a structured approach to mercury-related analysis in liquid hydrocarbon streams. UOP 938-20 is a practical reference for teams that need dependable documentation for sample review, quality verification, or technical assessment.

What is UOP 938-20?

UOP 938-20 is a UOP Test Method focused on the determination of total mercury and mercury species in liquid hydrocarbons. It is intended for analytical laboratory use and aligns with work where mercury presence must be evaluated with care in petroleum or chemical samples. As a method document, it helps define a consistent framework for measurement and reporting in a commercial testing environment. Buyers often review it when selecting an analytical method for liquid hydrocarbon characterization, trace contaminants review, or mercury-related laboratory documentation.

Where is UOP 938-20 used?

UOP 938-20 is commonly used in refinery laboratories, fuel testing facilities, and analytical chemistry groups that handle liquid hydrocarbon samples. It may also be relevant to QA/QC teams, petroleum specialists, and technical reviewers responsible for product qualification or sample assessment. In practice, the method supports workflows where mercury needs to be checked as part of routine laboratory analysis, process monitoring, or product evaluation. Organizations involved in hydrocarbon handling or specification review may use it to support more consistent test selection and documentation.

Why is UOP 938-20 important?

UOP 938-20 matters because mercury can be a critical trace concern in liquid hydrocarbons, affecting analytical review, quality decisions, and downstream compatibility considerations. Having a defined UOP method helps laboratories compare results more consistently and supports clearer technical communication across teams. For refinery and lab personnel, this can improve confidence in sample evaluation and reduce ambiguity when documenting mercury-related findings. It is especially useful when accurate, standardized laboratory support is needed for product comparison, routine quality control, or technical review.
