    Elemental Analysis for Automotive Catalyst Recycling – Reclaim Precious Metals

    Used catalytic converters are collected and recycled in order to reclaim the precious metals Pt, Rh and Pd. Typically, the entire honeycomb core is removed and ground into fine powder. Once in powder form, the precious metal catalysts can be extracted, or the powder can be sold to a refiner. The honeycomb core is typically ceramic, containing combinations of the elements Al, Si, Fe, Zn, Sr, Zr, Ba, La and Ce. Some cores can be made of a stainless steel honeycomb and so would contain higher Fe and other metals....

    Elemental Analysis for Wood Treatment by EDXRF / XRF

    The processes that are taken to prevent wood rot fall under the definition of wood preservation or timber treatment. There are a number of different chemical preservatives and processes that can extend the life of wood, timber, wood structures or engineered wood. These generally increase the durability and resistance from being destroyed by insects or fungus and/or allow the use of wood structures in wet or underwater conditions (marine grade wood). Applied Rigaku Technologies, Inc. specializes in EDXRF spectromet...

    Elemental Analysis for Mining & Refining by EDXRF / XRF

    Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an ore body, vein or (coal) seam. Materials recovered by mining include base metals, precious metals, iron, uranium, coal, diamonds, limestone, oil shale, rock salt and potash. Whether the determination entails measurement of ores, feed, slags, or tailings in the mining process, X-ray Fluorescence (XRF) spectroscopy is one of the most commonly employed technique for these routine determinations of metal...

    Elemental Analysis for Metals & Alloys by EDXRF / XRF

    Metal alloys are materials made of two or more metals, or of a metal and another material; therefore, mechanical properties like hardness and strength are attributed to a precise composition or stoichiometry. Chemical analysis is typically used as a basis for classifying metal and alloys, controlling their production processes, or verifying their designation. Energy Dispersive X-ray Fluorescence (EDXRF) is a routine used to identify and classify metals and alloys. Foundries, smelters, and mills, as well as...

    Steelmaking process monitoring by Direct MS

    Steel, an alloy of iron and carbon (up to 2% of weight), is one of the most widely used construction materials. It is produced by Basic Oxygen Steelmaking (BOS) in a converter : oxygen is blown to form carbon monoxide (CO) and carbon dioxide (CO2) with the carbon excess of molten pig iron. Other chemical elements (such as nitrogen) that may decrease the efficiency of furnace are also removed. Finally, oxygen is replaced by an inert gas (Ar) to minimize the oxidation.

    Elemental Analysis of Food, Cosmetics, Fertilizer, Feeds & Environment by EDXRF / XRF

    For characterization and remediation of contaminated soils, sediments, and sludges, EDXRF (XRF) analysis provides quick and reliable assays. Energy Dispersive X-ray Fluorescence is a standard technique recognized by the U.S. EPA and is routinely employed to determine heavy metal concentrations (RCRA metals) in soils and sediments. In addition to soils, Rigaku XRF spectrometers may use used with the UltraCarry technique to quantify trace metals in aqueous (water) samples down to part-per-billion levels. Rigaku's...

    Elemental Analysis for Geological Applications by EDXRF / XRF

    In studying the planetary processes and makeup of the Earth (geology), geologists routinely analyze the composition of rock and mineral samples. Rapid elemental analyses for sodium (Na) through uranium (U) can be accomplished, through the use of cost-effective, high-performance Energy Dispersive X-ray Fluorescence (EDXRF, XRF) instrumentation without destruction, digestion or alteration of the sample. Eliminating the need for a wet chemistry lab has made the EDXRF technique of particular interest to the geological...
