UOP 304-90 is a laboratory test method for determining the bromine number and bromine index of hydrocarbons by potentiometric titration. It is used to evaluate the presence of reactive unsaturation in hydrocarbon samples, helping laboratories compare product quality and assess feedstock or finished-product suitability. For buyers reviewing petroleum testing methods, this standard is relevant when consistent analytical results are needed for refinery QA/QC, fuel evaluation, and technical documentation. UOP 304-90 supports controlled measurement work where method consistency and clear reporting matter.

Overview of UOP 304-90

This UOP test method focuses on a measurement-based determination of bromine number and bromine index using potentiometric titration. In practical laboratory terms, it provides a standardized way to evaluate hydrocarbon samples for bromine-reactive components, which can be useful in product characterization and comparison. UOP 304-90 is typically reviewed by analytical chemists, laboratory analysts, and quality specialists who need a dependable method for petroleum and chemical sample assessment. Its value lies in offering a defined analytical approach for consistent documentation and interpretation.

Laboratory use of UOP 304-90

UOP 304-90 is commonly used in refinery and petrochemical laboratories where hydrocarbon samples must be checked against internal quality targets or customer specifications. It may support fuel testing programs, process sample review, and analytical method selection for teams that monitor product consistency. Laboratory analysts and refinery QA/QC personnel often rely on this type of method when comparing batches or verifying the chemical character of a sample. Because the title centers on potentiometric titration, it fits workflows that require careful, repeatable bench-level analysis.

Why UOP 304-90 matters in day-to-day work

In day-to-day operations, UOP 304-90 helps teams apply a clear analytical measure to hydrocarbon samples where bromine number or bromine index is relevant. That can improve product comparison, support quality review, and strengthen technical records used in refinery or laboratory decision-making. For organizations managing routine sample checks, a recognized UOP method can help reduce ambiguity between laboratories and simplify internal discussion of results. UOP 304-90 is therefore useful for maintaining analytical consistency and supporting practical quality-control workflows.
