UOP 874-88 is a laboratory test method for evaluating the pore size distribution of porous substances by nitrogen adsorption using a Quantachrome analyzer. For buyers comparing analytical standards, it supports characterization work where pore structure can affect performance, capacity, or consistency in materials used in petroleum, chemical, and related process environments. The method is relevant when a team needs a controlled way to review porous sample behavior and document results for technical assessment, product comparison, or quality verification. UOP 874-88 helps align laboratory analysis with a recognized UOP framework.

UOP 874-88 method scope

This UOP test method is focused on measuring pore size distribution in porous substances through nitrogen adsorption instrumentation. Its scope is centered on analytical evaluation of surface and pore characteristics rather than bulk composition. That makes it useful for laboratory work where material structure needs to be understood in a consistent, repeatable way. UOP 874-88 is generally suited to technical users who need a defined laboratory method for characterizing porous samples and comparing results across batches, suppliers, or development studies.

Where is UOP 874-88 used?

UOP 874-88 is commonly used in analytical laboratories, refinery support labs, and petrochemical research environments where porous materials are evaluated as part of qualification or review workflows. It may be relevant to laboratory analysts, analytical chemists, refinery QA/QC teams, and technical reviewers who need structured pore distribution data for sample assessment. The method can also support engineering teams involved in material selection or process-related studies when pore structure is an important performance factor. UOP 874-88 fits practical lab documentation and method selection needs.

Why professionals use UOP 874-88

Professionals use UOP 874-88 when pore structure needs to be described in a consistent and defensible way for technical decision-making. In day-to-day laboratory and quality workflows, it can support sample comparison, product review, and verification of material consistency. The method is valuable because pore size distribution often influences how a porous substance behaves in service or processing, making the analytical result useful beyond simple identification. For teams handling test records and review reports, UOP 874-88 provides a recognized framework for clearer documentation and more reliable comparisons.
