UOP 905-91

UOP 905-91 is a laboratory test method for Platinum Agglomeration by X-Ray Diffraction, designed to help technical teams evaluate platinum-related structural changes in a material by an established analytical technique. For buyers comparing UOP methods, this standard is relevant when platinum behavior, catalyst condition, or material characterization needs to be checked in a controlled laboratory setting. It supports disciplined analysis for refinery and petrochemical work where understanding agglomeration can matter for quality review, process monitoring, and technical documentation.

UOP 905-91 method scope

This UOP 905-91 method focuses on assessing platinum agglomeration using X-ray diffraction, placing it in the category of an instrumental laboratory method. Its purpose is to provide a defined analytical approach for examining platinum distribution or structural change in a sample, rather than broad compositional testing. In practical use, the method helps standardize how a laboratory evaluates material condition and compares results across samples, which is important when platinum-containing materials need consistent, defensible review.

Where is UOP 905-91 used?

UOP 905-91 is commonly used in analytical laboratories, refinery support labs, and technical review functions that work with platinum-containing materials or catalyst-related samples. It may be relevant to laboratory analysts, analytical chemists, refinery QA/QC teams, and process or product quality specialists who need a recognized method for X-ray diffraction-based evaluation. The method is most useful where controlled sample assessment, method consistency, and clear technical documentation are needed for internal review or material comparison.

Why professionals use UOP 905-91

Professionals use UOP 905-91 to bring consistency and clarity to platinum agglomeration assessment. In day-to-day laboratory and refinery workflows, a recognized UOP test method helps reduce ambiguity when reviewing results, comparing sample history, or documenting catalyst or material condition. It also supports technical decision-making by giving teams a standardized reference for analysis, which can be valuable for QA/QC review, laboratory reporting, and cross-checking product or process performance.
