UOP 845-90

UOP 845-90 is a technical laboratory method for Trace Alcohols in LPG by GC, giving buyers a clear reference for evaluating low-level alcohol content in liquefied petroleum gas. As a UOP test method, it supports analytical work where trace constituents may affect product quality, handling, or downstream processing decisions. For refinery QA/QC teams, laboratory analysts, and technical reviewers, this method helps define a consistent approach to trace alcohol assessment in LPG streams. UOP 845-90 is useful when selecting a standards document for routine sample review, method comparison, or quality verification.

Overview of UOP 845-90

This UOP method focuses on chromatographic analysis of trace alcohols in LPG, making it relevant to laboratory settings that require controlled measurement of minor components in hydrocarbon products. The official title indicates a GC-based analytical approach, which is commonly associated with precise separation and identification in petroleum testing workflows. UOP 845-90 is therefore suited to organizations that need a documented method for evaluating trace alcohol presence in LPG samples, supporting analytical chemistry work, product characterization, and technical documentation within refinery and fuel testing programs.

Laboratory use of UOP 845-90

UOP 845-90 may be used by laboratory analysts, fuel testing personnel, and refinery QA/QC teams working with LPG sample evaluation. It is especially relevant in environments where trace alcohols must be reviewed as part of routine quality control, incoming material checks, or product comparison activities. Petrochemical laboratories and technical review groups may also rely on this type of method when aligning analytical practice with internal specifications or customer requirements. For organizations managing LPG quality, the method provides a focused reference for chromatography-based trace analysis.

Why UOP 845-90 matters in day-to-day work

In day-to-day laboratory work, UOP 845-90 helps support consistent trace alcohol evaluation in LPG, which can improve confidence in analytical results and reporting. Having a defined UOP test method can make sample review more straightforward for teams that need clear documentation, repeatable laboratory practice, and reliable comparison across batches or sites. It is particularly valuable when technical staff need a recognized method reference for QA/QC decisions, product verification, or analytical recordkeeping. UOP 845-90 adds structure to routine testing and helps reduce ambiguity in method selection.
