UOP 543-97 is a chromatography method for the trace determination of non-aromatic hydrocarbons in high-purity aromatics. It is designed to help laboratories assess whether aromatic feedstocks or products contain low-level hydrocarbon impurities that can affect purity, product consistency, and specification review. For buyers evaluating analytical standards, this method is relevant to routine sample comparison, quality verification, and technical reporting in refinery and petrochemical lab settings. It supports controlled analysis where trace-level separation and clear identification are important for UOP 543-97 users.

Purpose of UOP 543-97

The purpose of UOP 543-97 is to provide a gas chromatography-based approach for measuring non-aromatic hydrocarbon content in high-purity aromatic materials. As a UOP chromatography method, it is intended to support analytical determination with a focus on trace impurity assessment rather than broad compositional profiling. This makes it useful when laboratories need a consistent way to examine aromatic products for small hydrocarbon contaminants that may influence product qualification, internal acceptance checks, or documentation of sample purity in technical workflows.

Laboratory use of UOP 543-97

UOP 543-97 is commonly suited to analytical laboratories that handle aromatic product testing, refinery quality control, and petrochemical sample review. It may be used by laboratory analysts, analytical chemists, and QA/QC teams responsible for verifying high-purity aromatics and checking trace non-aromatic hydrocarbon levels. In practice, the method supports routine chromatography work, comparison of samples across batches, and technical review of impurity-related results. It is a practical fit wherever consistent laboratory evaluation of aromatic purity is part of the workflow.

Practical value of UOP 543-97

The practical value of UOP 543-97 lies in its ability to support reliable trace impurity evaluation in high-purity aromatic streams. For professional teams, that means better analytical clarity when comparing samples, documenting results, and reviewing product quality trends. It can help reduce uncertainty in laboratory reporting by giving a defined method for identifying non-aromatic hydrocarbon content at low levels. For organizations that depend on consistent aromatic product quality, this method supports more confident technical decisions and more structured laboratory documentation.
