UOP 993-11 is a laboratory test method for measuring water in solids by furnace desorption with volumetric Karl Fischer titration. It is intended to support petroleum, refinery, and chemical sample evaluation where accurate moisture control can affect material handling, quality decisions, and technical comparisons. By combining thermal release of water from a solid with a proven titration approach, the method gives laboratories a structured way to assess moisture content in a controlled, documentable format. For buyers reviewing analytical standards, UOP 993-11 is relevant when water determination in solid materials is part of routine QA/QC or product review.

Overview of UOP 993-11

This UOP test method is focused on analytical measurement of water in solid samples using furnace desorption followed by volumetric Karl Fischer titration. The official title indicates a practical laboratory technique designed to isolate moisture from a solid matrix and quantify it with an established titrimetric method. In a petroleum or chemical testing environment, that makes UOP 993-11 useful for standardized moisture assessment, method selection, and technical documentation. It is especially relevant where consistent water measurement is needed for sample comparison, material evaluation, or controlled laboratory reporting.

Laboratory use of UOP 993-11

UOP 993-11 is commonly suited to laboratory workflows where solid materials must be checked for water content before or during quality review. That may include refinery and petrochemical laboratories, analytical chemistry groups, and technical teams responsible for sample acceptance or product characterization. Laboratory analysts and QA/QC personnel may use the method when moisture can influence handling, stability, or comparability of test results. Because it is built around furnace desorption and Karl Fischer titration, the method fits structured lab environments that need a clear, reproducible approach to water determination in solids.

Why UOP 993-11 matters in day-to-day work

In day-to-day work, UOP 993-11 helps teams keep water measurement in solid samples consistent and traceable. That supports more reliable comparisons between lots, clearer quality decisions, and better documentation for internal review or external reporting. For laboratory analysts, technical reviewers, and refinery QA/QC teams, a defined method reduces ambiguity when moisture content is part of acceptance testing or material evaluation. UOP 993-11 also matters because it ties a specific analytical need to a recognized UOP method, which can simplify method selection and improve confidence in routine laboratory results.
