AdBlue® (Urea AUS 32) is a critical component in reducing nitrogen oxide (NOx) emissions from diesel engines using Selective Catalytic Reduction (SCR) technology. This aqueous urea solution is injected into the exhaust stream, converting harmful pollutants into nitrogen and water. To guarantee its effectiveness and protect sensitive engine systems, AdBlue® quality is regulated under ISO 22241 standards, which define strict contamination limits for specific elements.
This application report outlines a robust methodology for multi-element analysis of AdBlue® using ICP-OES with a Dual Side-on plasma observation interface. Explore how the elemental analysis technique ensures compliance with ISO 22241-2 by delivering precise and accurate measurements of trace contaminants. Gain insights into detection limits, spike recovery studies, and control sample analyses to optimize quality control and maintain the integrity of AdBlue® products.
