UOP 976-02 is a laboratory test method for evaluating trace C4-C9 saturates in high purity aromatics by GC. It is designed to support analytical review where very low-level saturated hydrocarbon content may affect product specification, purity verification, or downstream use. For buyers comparing petroleum and chemical standards, this method is relevant when precise chromatographic assessment is needed for aromatic products. UOP 976-02 helps laboratories document trace hydrocarbon presence in a controlled, repeatable way that is suitable for quality-focused technical work.

Purpose of UOP 976-02

The purpose of UOP 976-02 is to provide a GC-based analytical approach for measuring trace C4-C9 saturates in high purity aromatics. As a UOP test method, it supports laboratory determination work where small amounts of saturates must be identified or quantified within aromatic matrices. This makes it useful for technical teams that need a consistent method for evaluating product purity, comparing samples, or reviewing aromatic material against internal quality expectations. It is a practical document for analytical chemists and QA/QC personnel working with refined or petrochemical samples.

Laboratory use of UOP 976-02

UOP 976-02 is commonly suited to refinery laboratories, petrochemical quality labs, and contract testing environments that handle high purity aromatic materials. It may be used by laboratory analysts, technical reviewers, and product quality specialists who need a defined GC method for trace saturate evaluation. In practice, it supports sample review, batch comparison, and documentation for aromatic product quality checks. For organizations that rely on chromatographic data to confirm specification conformity or investigate purity-related concerns, this method provides a focused technical basis for routine laboratory work.

Practical importance of UOP 976-02

UOP 976-02 matters because trace saturates in high purity aromatics can influence product interpretation, specification decisions, and quality records. A clear analytical method helps reduce ambiguity when teams compare lots, review incoming material, or verify that a product remains within expected purity targets. For laboratories and QA/QC groups, the method supports consistent reporting and better technical decision-making. It also helps maintain alignment between analytical results and operational quality requirements, which is important when aromatic products are being evaluated for further processing or customer use.
