UOP 549-09 is the method buyers look to when they need a practical way to evaluate sodium in petroleum distillates using instrumental analysis. Titled Sodium in Petroleum Distillates by ICP-OES or AAS, it supports laboratory measurement work where sodium levels may affect product quality, processing behavior, or downstream equipment considerations. For refinery laboratories, QA/QC teams, and analytical chemists, this type of UOP method helps standardize sample review and technical comparison across routine petroleum testing workflows. UOP 549-09 is especially useful when consistent, instrument-based data is needed for documentation and decision support.

UOP 549-09 analytical scope

This UOP 549-09 instrumental analysis method is focused on the determination of sodium in petroleum distillates by ICP-OES or AAS. Its scope is centered on laboratory measurement rather than process interpretation, making it relevant for analytical work that depends on controlled, repeatable results. Because the method is built around instrumental techniques, it is suited to teams that need a reliable framework for comparing distillate samples and generating technically defensible data. It fits well within petroleum testing programs that require clear analytical documentation and method consistency.

Where is UOP 549-09 used?

UOP 549-09 is commonly used in petroleum and refinery laboratory settings where distillate samples are checked for sodium as part of quality evaluation or technical review. It may be used by laboratory analysts, analytical chemists, and refinery QA/QC teams supporting fuel testing, sample qualification, or product comparison. Organizations involved in distillate handling, blending, or process oversight may also rely on this kind of method to support laboratory records and routine instrument-based assessment. The title points to a focused use case for petroleum distillates rather than broad-purpose elemental analysis.

Why labs rely on UOP 549-09

Labs rely on UOP 549-09 because sodium data can be important for product consistency, analytical clarity, and internal quality decisions. A defined UOP method helps teams align testing practices across instruments and operators, which is valuable when results are used in refinery workflows or technical documentation. For buyers managing petroleum sample evaluation, the method offers a structured approach to instrumental analysis that supports comparison, review, and recordkeeping. UOP 549-09 also helps reduce ambiguity when sodium results need to be communicated across laboratory and operational teams.
