UOP 870-90 is a laboratory test method for determining the carbon number distribution of paraffins, naphthenes, and aromatics by GC. For buyers comparing analytical standards, it is relevant when detailed hydrocarbon-type profiling is needed for petroleum, refinery, or chemical sample evaluation. This method supports more informed product characterization by separating major hydrocarbon families and showing how carbon number distribution varies across a sample. UOP 870-90 is a practical choice for teams that need structured chromatographic analysis for quality review, technical comparison, or documentation in routine laboratory workflows.

What is UOP 870-90?

This UOP method is an analytical gas chromatography procedure focused on measuring the carbon number distribution of paraffins, naphthenes, and aromatics. In practice, it is used to characterize hydrocarbon composition in a way that supports laboratory interpretation and product understanding. As a UOP Test Method, UOP 870-90 is best viewed as a technical tool for structured GC-based analysis rather than a general-purpose description. It is useful when a lab needs a consistent way to review hydrocarbon family distribution in petroleum or related process samples.

Where is UOP 870-90 used?

UOP 870-90 is commonly used in petroleum and petrochemical laboratory settings where hydrocarbon composition needs to be reviewed in a controlled analytical environment. It may be relevant for refinery QA/QC teams, laboratory analysts, analytical chemists, and technical reviewers responsible for sample characterization or method selection. The method can support product evaluation, process sample review, and internal comparison work where carbon number distribution data helps inform decisions. It is particularly useful when GC-based documentation is needed for hydrocarbon-type profiling.

Why is UOP 870-90 important?

UOP 870-90 matters because it gives technical teams a focused way to assess hydrocarbon distribution across paraffins, naphthenes, and aromatics. That information can improve product comparison, support quality control, and help clarify differences between samples during laboratory review. For refinery and petroleum testing teams, a clear analytical method also helps maintain consistent documentation and communication across operations. UOP 870-90 is valuable when decision-making depends on reliable chromatographic characterization rather than broad compositional estimates.
