UOP 387-62 is a laboratory method for determining arsenic in petroleum stocks and catalysts by spectrophotometry, making it relevant when trace contamination and catalyst condition need to be checked with care. As a UOP 387-62 test method, it supports technical review in petroleum and chemical labs where arsenic can affect process performance, catalyst life, and product acceptance decisions. The withdrawn 2011 status also makes it useful as a reference standard for historical comparison, archived procedures, or document control in organizations that manage legacy analytical methods.

UOP 387-62 method scope

This UOP test method focuses on arsenic measurement in petroleum stocks and catalyst materials using a spectrophotometric approach. Its scope is centered on analytical evaluation rather than broad product characterization, so it is best suited to laboratories that need a defined method for trace arsenic assessment. UOP 387-62 is typically reviewed alongside other petroleum testing documents when teams need consistent analytical language, method selection support, or a controlled reference for quality and compliance records.

Where is UOP 387-62 used?

UOP 387-62 is generally used in petroleum and refinery laboratory settings where arsenic testing supports sample review, catalyst monitoring, and quality checks on process materials. It may be relevant to laboratory analysts, analytical chemists, refinery QA/QC teams, and technical reviewers who evaluate catalyst exposure or contamination concerns. In practice, the method can assist with routine lab documentation, process sample assessment, and internal comparison work tied to petroleum stocks and catalyst-related testing programs.

Why professionals use UOP 387-62

Professionals use UOP 387-62 when they need a clear, recognized reference for arsenic analysis in petroleum-related materials. For day-to-day laboratory work, it helps support consistent reporting, technical traceability, and more confident comparison between samples or batches. The method is especially useful where small changes in arsenic content may matter to process performance or catalyst behavior. For teams managing legacy procedures, it also provides an established document for method review, archived testing records, and controlled technical reference.
