Catalytic converters in cars are used for reduction of hazardous emissions, such as carbon monoxide (CO), hydrocarbons (HxCy) and nitrogen oxides (NOx). These harmful substances are converted into neutral carbon dioxide (CO2), water and nitrogen by catalytic chemical reactions, which are accelerated by three platinum group metals (PGM): platinum, palladium, and rhodium.
Due to a great number of car catalyst types, an amount of PGM’s varies significantly. The fast and accurate testing method is required for the PGM’s content evaluation. XRF provides precise and fast catalytic converters analysis for simple sorting and price evaluation. Usually, a concentration of PGM’s in a car catalyst is much higher, than in ores.
With ElvaX spectrometers it takes just seconds to give the result as opposed to hours or days as in a laboratory. Together with simple operation training and easy sample preparation, they are ideal tools for the daily business for quality control and price evaluation during catalyst’s buying and selling.
