UOP 1023-18 is a laboratory determination method for measuring trace arsine and phosphine in polymer grade ethylene and propylene by gas chromatography mass spectrometry. It is intended for buyers who need a standardized way to evaluate very low-level toxic impurities in light olefin streams, where even trace contamination can affect product suitability and handling. For petrochemical laboratories, refinery QA/QC groups, and analytical teams, this method supports consistent sample review, quality verification, and technical documentation when screening polymer grade feedstocks or products.

Overview of UOP 1023-18

This UOP determination method focuses on the analytical measurement of arsine and phosphine in polymer grade ethylene and propylene. The title indicates a GC-MS-based approach, which makes the method relevant to laboratories that rely on instrumental analysis for trace impurity screening. In practice, UOP 1023-18 helps define a repeatable reference for evaluating gas streams where very low concentrations of these compounds matter. It is suited to technical environments that need a clear, standardized method for product assessment and laboratory comparison.

Laboratory use of UOP 1023-18

UOP 1023-18 is commonly relevant in petrochemical and gas analysis laboratories that support polymer grade olefin production and quality review. Laboratory analysts, quality control personnel, and technical reviewers may use it when checking ethylene or propylene samples for trace arsine and phosphine. The method also fits routine analytical workflows where standardized determination is needed for product release support, internal comparison, or documentation. Its value is highest in settings that require careful trace-level assessment of process or finished product samples.

Why UOP 1023-18 matters in practice

This method matters because trace arsine and phosphine can be critical quality concerns in polymer grade olefin service. A consistent determination method helps laboratories compare results more reliably, support internal quality control, and maintain clear technical records. For teams responsible for product quality, analytical chemistry, or process verification, UOP 1023-18 provides a recognized reference point for evaluating sample suitability and maintaining confidence in laboratory reporting. It is especially useful where repeatable low-level impurity assessment is part of day-to-day decision making.
