UOP 836-82 is a laboratory test method for measuring sulfur in distillate and residual oils by X-ray fluorescence. For buyers evaluating petroleum testing standards, it provides a focused approach for assessing sulfur content in liquid hydrocarbon samples where sulfur control matters for product quality, compliance review, and process monitoring. This method is relevant to refinery and analytical teams that need a clear, standardized way to compare samples and support routine fuel or oil characterization. As a UOP 836-82 method, it fits technical workflows that depend on consistent laboratory documentation and practical sulfur analysis.

UOP 836-82 method scope

The scope of UOP 836-82 is centered on sulfur determination in distillate and residual oils using X-ray fluorescence. It is an instrumental laboratory method intended for petroleum and related oil samples where sulfur evaluation is part of routine analysis or quality verification. The method title indicates a direct analytical focus on sulfur content rather than broader compositional testing, making it suitable for organized lab work, specification checks, and method selection in refinery environments. UOP 836-82 is therefore best viewed as a targeted measurement standard for sulfur analysis in oils.

Where is UOP 836-82 used?

UOP 836-82 is commonly used in petroleum laboratories, refinery QA/QC programs, and technical review settings that handle distillate or residual oil samples. Laboratory analysts and analytical chemists may use it during routine sample evaluation, while refinery quality teams may rely on it for sulfur-related product checks and internal documentation. It can also support fuel testing and process-related sample review where sulfur levels are an important parameter. For organizations that manage oil characterization or compliance-oriented testing, UOP 836-82 helps align laboratory practice with a recognized UOP method.

Why professionals use UOP 836-82

Professionals use UOP 836-82 because sulfur results often influence product comparison, quality decisions, and technical reporting. A standardized X-ray fluorescence method helps laboratories maintain consistency across batches and sample types, which is important when comparing distillate and residual oils over time. Refinery and testing teams value methods like this for clearer documentation, more efficient workflow alignment, and dependable analytical review. In day-to-day practice, UOP 836-82 supports sulfur screening and verification with a method framework that is familiar to petroleum and laboratory specialists.
