UOP 1035-19 is a laboratory determination method for measuring trace chloromethane, chloroethene, and dichloromethane in polymer grade ethylene and propylene by gas chromatography mass spectrometry. For buyers evaluating analytical standards, it provides a focused reference for checking low-level halogenated impurities that can affect product quality and downstream processing. This makes the method relevant for laboratory analysts, refinery and petrochemical QA/QC teams, and technical reviewers who need repeatable trace analysis for polymer feedstocks and product verification.

Purpose of UOP 1035-19

The purpose of UOP 1035-19 is to support consistent measurement of specific volatile chlorinated compounds in polymer grade olefin streams. As a determination method, it centers on analytical quantification rather than broad product characterization, helping laboratories identify whether ethylene or propylene samples meet internal quality expectations. The method title indicates a gas chromatography mass spectrometry approach, which is typically used when trace-level selectivity and reliable compound identification are important in routine laboratory analysis and technical documentation.

Laboratory use of UOP 1035-19

UOP 1035-19 may be used in petrochemical and refinery laboratory workflows where polymer grade ethylene and propylene are reviewed for trace contaminant control. It is especially relevant for analytical chemists, laboratory analysts, and product quality teams responsible for sample evaluation, release support, or comparison against internal specifications. The method also fits technical review activities where precise identification of chloromethane, chloroethene, and dichloromethane helps confirm product consistency and supports defensible laboratory reporting.

Practical value of UOP 1035-19

In day-to-day use, UOP 1035-19 helps teams maintain clearer control over trace impurities that can matter in polymer feedstock handling and quality verification. A standardized determination method supports more consistent results across laboratories, which is useful for trending, product comparison, and review of analytical data over time. For QA/QC personnel and technical managers, it provides a practical basis for documenting trace chlorinated species with better repeatability and more confidence in routine testing decisions.
