UOP 690-13 is a UOP test method for analyzing C8 and lower boiling paraffins and naphthenes in low-olefin hydrocarbons by GC. It is intended for laboratories that need a structured way to evaluate light hydrocarbon compositions where paraffinic and naphthenic content can affect product quality, stream classification, and downstream processing decisions. For refinery QA/QC teams, petroleum analysts, and technical reviewers, this method supports clearer sample characterization and more consistent comparison of hydrocarbon streams. Its value lies in providing an analytical basis for reviewing low-boiling hydrocarbon materials with practical precision.

UOP 690-13 method scope

The scope of UOP 690-13 centers on gas chromatographic analysis of low-olefin hydrocarbons to assess C8 and lighter boiling paraffins and naphthenes. As an instrumental UOP method, it is suited to laboratory evaluation where composition detail is needed for technical judgment rather than simple routine screening. The method title indicates a focus on specific hydrocarbon families in the lighter boiling range, making it relevant when a buyer needs reliable compositional information for sample identification, product comparison, or refinery documentation. It is best viewed as a targeted analytical method for petroleum and hydrocarbon testing workflows.

Where is UOP 690-13 used?

UOP 690-13 is commonly used in refinery and petrochemical laboratories, as well as by fuel testing and product quality teams that handle light hydrocarbon streams. It may also be relevant to analytical chemists and process support personnel who review GC data for stream characterization or technical validation. Because the method addresses paraffins and naphthenes in low-olefin hydrocarbons, it fits environments where composition detail helps support QA/QC decisions, sample review, and internal reporting. UOP 690-13 is especially useful when laboratory results must be interpreted consistently across technical and quality functions.

Why professionals use UOP 690-13

Professionals use UOP 690-13 to add analytical clarity to hydrocarbon evaluation and to support consistent decisions in laboratory and refinery workflows. The method helps teams compare samples, document composition, and review light hydrocarbon streams with a standardized approach. That makes it valuable for quality control, technical audits, and product assessment where reliable GC-based information matters. For organizations working with low-olefin hydrocarbons, the method can improve confidence in reported composition and help align laboratory results with operational or commercial requirements. UOP 690-13 is also useful for maintaining traceable technical documentation.
