UOP 931-10

UOP 931-10 is a laboratory test method for Trace Impurities in Mixed Xylenes by GC, giving technical teams a structured way to evaluate low-level contaminants in this aromatic product stream. For buyers comparing analytical methods, it is relevant when product purity, feedstock review, or quality verification depends on identifying trace-level components that can affect downstream use. UOP 931-10 is especially useful where chromatography-based testing supports refinery QA/QC, petrochemical sample review, and routine laboratory documentation for mixed xylenes.

UOP 931-10 method scope

This UOP 931-10 test method is focused on analytical measurement of trace impurities in mixed xylenes using gas chromatography, as indicated by the official title. It is intended for laboratory environments that need a consistent way to examine the impurity profile of a mixed xylene sample rather than a broad compositional summary. The method is suited to controlled analytical work where trace components matter for product evaluation, method selection, and technical reporting. As a UOP method, it supports standardized laboratory practice for this specific material.

Where is UOP 931-10 used?

UOP 931-10 is commonly relevant in refinery and petrochemical laboratories that handle mixed xylenes, particularly where analytical chemists and laboratory analysts support QA/QC or product qualification workflows. It may also be used by technical reviewers and process or product quality teams when trace impurity data is needed for sample comparison, shipment review, or internal documentation. In practice, it fits environments where chromatography results help confirm whether a mixed xylene stream meets internal specifications or is suitable for further processing or commercial evaluation.

Why professionals use UOP 931-10

Professionals use UOP 931-10 because trace impurity information can materially influence product acceptance, process decisions, and downstream performance in mixed xylene applications. A defined GC-based method helps teams compare results consistently across batches, laboratories, or suppliers, which is valuable for quality control and technical review. For organizations working with aromatics, the method also supports clearer analytical records and more reliable interpretation of sample condition. That makes it a practical reference for day-to-day laboratory decision support and documentation.
