UOP 864-89 describes a laboratory method for measuring sulfur in organic and inorganic materials by combustion and IR detection. For buyers evaluating analytical standards, it is relevant wherever sulfur control, product verification, or compliance-oriented testing is part of routine work. The method title signals a practical analytical approach that can support refinery QA/QC, petroleum sample review, and chemical laboratory documentation. UOP 864-89 is therefore useful to teams that need a clear reference for sulfur determination in mixed material types and a standardized basis for comparison across internal testing programs.

What is UOP 864-89?

UOP 864-89 is a UOP test method focused on sulfur measurement through combustion followed by infrared detection. In practical terms, it is an analytical method for determining sulfur content in organic and inorganic materials using a defined laboratory approach. That makes it relevant to users who need a consistent technical reference for sulfur analysis rather than a broad product specification. As a UOP method, it is suited to controlled laboratory environments where clear method selection, repeatable analysis, and documented results are important.

Where is UOP 864-89 used?

This method is commonly used in petroleum, refinery, and chemical laboratory settings where sulfur levels need to be checked in materials that may vary in composition. Laboratory analysts, refinery QA/QC teams, and technical reviewers may rely on it when reviewing incoming samples, comparing product lots, or supporting internal quality records. UOP 864-89 is also relevant in process or product evaluation workflows where sulfur data helps guide material acceptance, documentation, or follow-up testing. Its title makes it especially suitable for teams handling diverse organic and inorganic sample types.

Why is UOP 864-89 important?

UOP 864-89 matters because sulfur measurement is often a key part of product control and analytical decision-making. A defined combustion and IR detection method helps support consistent laboratory practice, clearer comparisons between samples, and more reliable technical review. For organizations managing quality checks, method libraries, or test documentation, this UOP method provides a focused reference tied directly to sulfur analysis. UOP 864-89 can help laboratories maintain a more orderly workflow when sulfur results are needed for reporting, screening, or internal verification.
