UOP 755-13 is a UOP method for the GC-based evaluation of trace impurities in high purity ethyl benzene, helping laboratories identify whether the material meets tight product-quality expectations. For buyers comparing analytical standards, this method is relevant when low-level contaminants can affect downstream use, specification review, or product acceptance. UOP 755-13 supports controlled laboratory assessment of a high-purity aromatic feed or product, giving analytical teams a clear framework for checking impurity presence in a technically consistent way. It is a practical reference for quality-focused testing and documentation.

Purpose of UOP 755-13

The purpose of UOP 755-13 is to provide a defined gas chromatography test method for assessing trace impurities in high purity ethyl benzene. As an instrumental UOP test method, it is aimed at analytical measurement under controlled laboratory conditions rather than broad compositional screening. This makes it useful for organizations that need a focused method for impurity evaluation, product qualification, or internal specification support. The method is especially relevant where purity level and small contaminant differences matter in chemical or petroleum-related quality decisions.

Laboratory use of UOP 755-13

UOP 755-13 is commonly suited to analytical laboratories handling high purity ethyl benzene samples for routine quality checks, incoming material review, or release testing. It may be used by laboratory analysts, analytical chemists, and refinery or petrochemical QA/QC teams that need dependable impurity data for technical review. Because the method centers on GC analysis, it fits workflows where chromatographic documentation and sample comparison are part of standard laboratory practice. It can also support method selection when trace-level impurity control is important to a product program.

Practical importance of UOP 755-13

In day-to-day use, UOP 755-13 helps teams maintain consistency when reviewing the purity of ethyl benzene and checking for trace impurities that may influence product quality. It supports clearer analytical reporting, more consistent comparison between batches, and better alignment between laboratory results and specification-based decisions. For technical staff, the method can improve confidence in product evaluation and reduce ambiguity during quality verification. UOP 755-13 is therefore useful wherever trace impurity control is part of refinery, chemical, or laboratory quality management.
