UOP 197-89 is the UOP 197-89 test method for Mercaptan Sulfur - Copper Number, a laboratory standard used to evaluate sulfur-related behavior in petroleum and chemical samples. By focusing on mercaptan sulfur and the copper number concept, this method helps professionals assess sample characteristics that can affect product quality, handling, and technical review. It is a practical reference for organizations that need a consistent analytical approach when reviewing sulfur-sensitive materials, supporting method selection, laboratory documentation, and refinery or plant quality decisions.

Purpose of UOP 197-89

The purpose of UOP 197-89 is to provide a defined test method for evaluating mercaptan sulfur through the copper number framework. As a UOP test method, it serves as a structured analytical reference for laboratories that need a repeatable way to characterize sulfur-related properties in petroleum or chemical samples. This makes it relevant where sulfur content or mercaptan behavior must be compared, recorded, or reviewed as part of routine analytical chemistry and product assessment work.

Laboratory use of UOP 197-89

UOP 197-89 is commonly relevant in laboratory and refinery settings where analysts and QA/QC teams review sulfur-sensitive streams, process samples, or finished products. Technical staff may use it during sample evaluation, specification support, or internal comparison of materials that require mercaptan sulfur assessment. It can also be useful for petroleum specialists, analytical chemists, and quality reviewers who need an established UOP method to support consistent documentation and technical interpretation across laboratory workflows.

Practical importance of UOP 197-89

In day-to-day professional use, UOP 197-89 helps support clearer product characterization and more consistent laboratory decision-making. For teams responsible for quality control or technical review, a defined method for Mercaptan Sulfur - Copper Number can improve comparison between samples, strengthen documentation, and reduce ambiguity in analytical reporting. It is especially valuable when sulfur-related behavior matters to product acceptance, refinery monitoring, or internal specification checks, where a recognized UOP method adds confidence to the evaluation process.
