UOP 894-91 is a laboratory test method for Mercury in Catalysts by GF-AAS, giving technical teams a focused way to evaluate mercury content in catalyst materials. For refineries, petrochemical plants, and analytical laboratories, this kind of method supports controlled sample assessment where trace mercury may affect handling, quality review, or downstream process decisions. UOP 894-91 is most relevant to buyers who need a recognized UOP method for catalyst analysis, especially when consistent documentation and method alignment matter in routine laboratory work or technical verification.

Purpose of UOP 894-91

The purpose of UOP 894-91 is to provide a standardized analytical approach for measuring mercury in catalysts using GF-AAS, or graphite furnace atomic absorption spectrometry. As a UOP Test Method, it is intended for laboratory use where mercury determination in catalyst samples must be handled with consistency and technical control. This supports analytical chemists, laboratory analysts, and quality-focused teams that need a defined method for trace-level evaluation and method-based reporting in petroleum and chemical testing environments.

Laboratory use of UOP 894-91

In practice, UOP 894-91 may be used in refinery laboratories, catalyst testing labs, and other technical settings that review catalyst composition or trace contaminant content. It is a practical fit for QA/QC groups, lab analysts, and technical reviewers who need a reliable method reference for mercury measurement in catalyst samples. The method can also support internal comparisons, routine sample review, and documentation workflows where mercury analysis is part of broader petroleum or chemical laboratory operations.

Practical importance of UOP 894-91

UOP 894-91 matters because mercury in catalysts is a meaningful quality and handling concern in technical operations. A clear test method helps teams compare results consistently, support laboratory quality control, and document analytical findings with confidence. For organizations managing catalysts across refinery or petrochemical workflows, this method can aid decision-making by providing a recognized basis for mercury evaluation. It is especially useful when analytical clarity and method consistency are important to internal review or product verification.
