UOP 938-00

UOP 938-00 is a petroleum laboratory method for evaluating total mercury and mercury species in liquid hydrocarbons. For buyers responsible for hydrocarbon quality and contaminant control, this standard is relevant when mercury monitoring must support product handling, technical review, or refinery decision-making. The method title indicates both total mercury and speciation coverage, which can help laboratories distinguish overall presence from the form of mercury detected in a liquid hydrocarbon sample. UOP 938-00 is therefore a practical reference for teams that need consistent analytical documentation around mercury in refinery, fuel, or petrochemical streams.

UOP 938-00 method scope

This UOP test method focuses on the measurement of total mercury and mercury species in liquid hydrocarbons. As a laboratory analytical method, it is intended to support evaluation of hydrocarbon samples where mercury content may affect product quality, processing concerns, or technical assessment. The scope is centered on trace contaminant analysis rather than broad compositional testing, making it useful for laboratories that need a defined approach to mercury-related characterization. UOP 938-00 is most relevant when precise documentation of mercury behavior in liquid hydrocarbon materials is part of the testing program.

Where is UOP 938-00 used?

UOP 938-00 is commonly used in refinery and petroleum laboratory environments where liquid hydrocarbon samples are reviewed for mercury content. It may be selected by laboratory analysts, QA/QC personnel, and technical reviewers involved in fuel testing, process sample review, or product quality verification. Chemical and refinery teams can use it as part of routine analytical documentation when mercury information is needed for internal assessment or external reporting. The method is also relevant in petrochemical settings where hydrocarbon feedstocks or finished products require controlled laboratory evaluation.

Why professionals use UOP 938-00

Professionals use UOP 938-00 when mercury information needs to be measured and documented in a clear, standardized way. In day-to-day lab work, that can support sample comparison, quality control review, and decisions tied to handling or downstream processing of liquid hydrocarbons. Because the method addresses both total mercury and mercury species, it can add useful detail for technical teams that need more than a single contaminant result. For organizations managing petroleum product quality, the standard helps improve consistency in analytical reporting and internal review.
