UOP 699-09 is a laboratory method for sodium in liquefied petroleum gas by ICP-OES or AAS, giving technical teams a focused way to evaluate sodium content in LPG samples. For buyers comparing instrumental methods, it supports consistent elemental analysis where trace sodium may affect product quality, handling, or downstream processing expectations. As a UOP instrumental analysis method, it is relevant to refinery and petrochemical laboratories that need a clear, documented approach for routine sample review, method selection, or technical verification. UOP 699-09 is useful when sodium measurement must be handled with controlled laboratory practice and dependable analytical reporting.

What does UOP 699-09 measure?

UOP 699-09 measures sodium in liquefied petroleum gas using an instrumental analytical approach, with ICP-OES or AAS named in the official title. That makes it a practical method for elemental determination in an LPG matrix, rather than a broad fuel characterization standard. The method is suited to laboratory work where sodium content needs to be checked as part of product evaluation, contamination review, or quality documentation. For analytical chemists and laboratory analysts, it provides a clear basis for comparing results across instrumental workflows and maintaining method consistency.

Where is UOP 699-09 used?

This method is typically used in refinery laboratories, petrochemical testing facilities, and other analytical settings that handle liquefied petroleum gas. It is relevant for teams responsible for QA/QC, laboratory analysis, and technical review of LPG samples. In practice, UOP 699-09 may support routine product monitoring, incoming or outgoing sample evaluation, and documentation for specification-related decisions. It is also useful when a laboratory needs a recognized UOP method aligned with instrumental measurement of sodium for internal comparison or external reporting.

Why is UOP 699-09 important?

UOP 699-09 matters because sodium in LPG can be an important quality and process consideration, and a defined instrumental method helps keep results comparable and defensible. For laboratories and refinery teams, it supports clearer decision-making by reducing ambiguity around how sodium is measured and documented. That can improve consistency across sample sets, strengthen technical reviews, and help QA/QC personnel assess product condition with greater confidence. As a standards document, it also supports method control and laboratory traceability in day-to-day petroleum testing work.
