UOP 816-80, Refractive Index of Hydrocarbon Liquids, is a laboratory test method for evaluating the refractive index of liquid hydrocarbon samples. This property is often useful as a quick technical indicator for sample characterization, comparison, and quality review in petroleum and chemical work. For buyers reviewing UOP 816-80, the value lies in its support for routine analytical decisions where a consistent optical property measurement can help distinguish, compare, or document hydrocarbon liquids. It is a practical method for laboratories that need a recognized reference for this type of measurement.

Overview of UOP 816-80

UOP 816-80 focuses on the refractive index of hydrocarbon liquids, making it a measurement-oriented UOP test method rather than a broad compositional analysis. In practice, this type of method is used when a laboratory needs a standardized way to assess an optical property that can support sample identification, product comparison, or technical screening. As a petroleum and chemical laboratory method, it fits work where reliable property data are needed for documentation and review. UOP 816-80 is therefore relevant to teams that depend on clear, repeatable analytical results.

Laboratory use of UOP 816-80

UOP 816-80 may be used in refinery laboratories, petroleum testing facilities, and petrochemical quality control settings where hydrocarbon liquid samples are checked against expected property behavior. Laboratory analysts and QA/QC personnel may use it during routine sample evaluation, while technical reviewers and product quality teams may rely on the result for comparison or verification work. Because the method is centered on a single physical property, it is well suited to workflows that need a concise, standardized test for liquid hydrocarbon characterization and analytical documentation.

Why UOP 816-80 matters in day-to-day work

In day-to-day laboratory work, UOP 816-80 helps provide a consistent reference point for evaluating hydrocarbon liquids. That can matter when teams are comparing lots, reviewing product identity, or checking whether a sample behaves as expected in a quality control program. For refinery and laboratory personnel, a clear refractive index measurement supports better technical judgment and cleaner records. It also helps reduce ambiguity when results are shared across analysts, shifts, or review groups, making the method useful for practical decision support and documentation control.
