    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...

    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 Rubber, Plastics & Polymers by EDXRF / XRF

    Polymer and plastics are materials composed of repeating hydrocarbon structural units, typically connected by covalent chemical bonds. Today polymers can be found everywhere, a range of applications that far exceeds that of any other traditional material from packaging materials, adhesives, foams, plastic containers, textiles, fibers and construction parts in airplanes and automobiles. The list of polymers includes: Rubber, Bakelite, Neoprene, Polypropylene (PP), Polystyrene (PS), High impact polystyrene (HIPS),...

    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 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...

    Elemental Analysis for RoHS & WEEE by EDXRF / XRF

    European Union (EC) environmental legislation contributes towards a better environment but has significant implications for many manufacturing companies in terms of marketing, design, manufacturing and "end-of-life" recovery and recycling. The Directives on Waste Electrical and Electronic Equipment (WEEE), 2002/96/EC, and the Restriction of Use of Certain Hazardous Substances (RoHS), 2002/95/EC, will require producers to recycle waste electrical/electronic equipment and remove certain hazardous substances....

  • Analysis of Methylimidazoles in Caramel Colored Carbonated Beverages

    Caramel colorings are used as additives in a broad range of food and beverage products to impart a desired color, but have no nutritional or preservative function. Recently, the potential hazard to humans of ammonia- and ammonia-sulfite-process caramel colorings was raised, because they contain the by-product 4-methylimidazole, which is a potential carcinogen.1 The methylimidazole compounds are difficult to analyze due to their polar nature and low molecular weight. Traditional reversed phase techniques are...

  • Environmental Monitoring

    Environmental monitoring is becoming more important every day in local, national and international policies, showing the environmental awareness demanded by society. This fact gives rise to an increase in the amount of legislation that obliges companies to law enforcement. Thus, the necessity of making more pollutants controls means high analysis expenses to the companies, which need to subcontract this service. Although applications in this area advance, there is still a clear demand to get new portable and...
