UOP 823-90 is a laboratory test method for determining platinum in fresh platinum-rhenium catalysts by spectrophotometry. For buyers evaluating catalyst quality documentation, this method helps define whether a sample meets the expected platinum content profile for fresh catalyst materials. It is a practical reference for organizations that need consistent analytical control of catalyst composition before use in refinery or chemical processing service. UOP 823-90 is especially relevant where catalyst verification, supplier comparison, and technical review depend on a recognized UOP method.

UOP 823-90 method scope

This UOP test method focuses on the analytical measurement of platinum in fresh platinum-rhenium catalyst samples using spectrophotometric evaluation. Its scope is centered on laboratory determination rather than process operation, making it suitable for controlled analytical work and method-based quality checks. Because the title identifies fresh platinum-rhenium catalysts specifically, the method is best understood as a composition verification tool for new catalyst material. It supports consistent lab assessment when platinum loading or catalyst identity must be documented with an established UOP method.

Where is UOP 823-90 used?

UOP 823-90 is commonly used in analytical laboratories, refinery support labs, and catalyst quality functions where fresh platinum-rhenium catalysts are received, reviewed, or released. Laboratory analysts and analytical chemists may use it during incoming material checks, while refinery QA/QC and technical reviewers may rely on it for supplier documentation and internal specification review. It is also relevant to process and petroleum specialists who need confidence in catalyst composition before the material enters a controlled operational program. The method fits environments that value standardized catalyst analysis.

Why professionals use UOP 823-90

Professionals use UOP 823-90 when they need a recognized way to confirm platinum content in fresh platinum-rhenium catalysts and support clear technical records. The method helps teams compare lots, verify product consistency, and maintain dependable laboratory documentation around catalyst composition. In day-to-day work, that can improve review of incoming materials, reduce ambiguity in quality discussions, and support decisions that depend on accurate catalyst characterization. For organizations managing precious-metal catalyst inventories, the method provides a focused analytical reference for internal control and communication.
