Automotive urea plays an extremely important role in enabling selective catalytic reduction (SCR) systems to reduce the environmental impact of diesel vehicles. These systems work by injecting a specific amount of urea into the exhaust gas stream. As the urea passes through the SCR catalyst converter, it decomposes into ammonia and carbon dioxide (CO2). The ammonia then reacts with the NOx in the catalyst to transform it into nitrogen and water vapor, two less toxic compounds. This reduces environmental pollution.

Monitoring and ensuring the quality of automotive urea to avoid contamination is also essential for preventing SCR system failures while complying with environmental regulations.

We provide automotive urea analysis based on ISO 22241-2, a document that specifies the test methods required for the determination of the quality and chemical characteristics of the NOx reducing agent AUS 32, urea in aqueous solution, as specified in ISO 22241-1.
