UOP 703-98 is the method for Carbon on Catalysts by Induction Furnace Combustion and Infrared Detection, giving laboratories a standardized way to assess carbon on catalyst samples. For refinery and petrochemical users, this matters because carbon buildup is a key indicator of catalyst condition and process performance. UOP 703-98 supports consistent laboratory evaluation when teams need a controlled analytical method for comparing catalyst samples, reviewing operating impacts, or documenting quality-related findings. It is especially relevant where accurate carbon measurement helps support technical decisions in catalyst management and routine plant laboratory work.

UOP 703-98 method scope

This UOP test method focuses on measuring carbon on catalysts using induction furnace combustion with infrared detection. In practical terms, it is an instrumental laboratory method designed to quantify carbon-related material on catalyst samples in a repeatable way. The scope is aligned with analytical chemistry workflows used for catalyst characterization and quality review rather than broad process testing. UOP 703-98 is therefore suited to professional users who need a defined method for evaluating catalyst condition, sample-to-sample differences, and carbon accumulation trends in controlled laboratory settings.

Where is UOP 703-98 used?

UOP 703-98 is commonly used in refinery and petrochemical laboratories that handle catalyst sample analysis. It may be relevant to laboratory analysts, refinery QA/QC teams, analytical chemists, and technical reviewers who need reliable carbon-on-catalyst data for documentation or process support. The method fits environments where catalyst performance, regeneration status, or operating history must be reviewed with consistent laboratory evidence. It can also support technical teams comparing catalyst samples across campaigns, units, or testing programs where carbon measurement is part of routine evaluation.

Why professionals use UOP 703-98

Professionals use UOP 703-98 because it provides a focused, standardized way to measure carbon on catalysts, which helps improve consistency in laboratory reporting and technical review. In day-to-day work, that can support clearer comparisons between samples, better tracking of catalyst condition, and more dependable quality-control documentation. For teams responsible for catalyst performance or refinery lab testing, the method offers a practical analytical reference that helps reduce ambiguity when carbon accumulation is part of the assessment. UOP 703-98 is valuable when reliable catalyst data is needed for operational decisions and recordkeeping.
