Analysis of Impurities in Lead Sponsored by PerkinElmerFeb 19 2021 Lead (Pb) is extremely toxic to living organisms, prompting this element to be phased out of an array of products. However, Pb is still frequently employed in a number of applications, most notably alloys, lead-acid batteries, radiation shielding, ammunition, flashing in the construction industry and as lining in industrial pipes and baths designed to carry corrosive substances. To accommodate this wide range of uses, an equally wide range of grades and purity levels of lead are produced. The London Metal Exch...

Analysis of Impurities in Gold Sponsored by PerkinElmerFeb 19 2021 Gold (Au) is able to be easily formed into a variety of shapes (such as thin sheets and wires or intricate shapes), can conduct electricity and is resistant to corrosion, a unique combination of characteristics that make it one of the most useful metals on earth, besides one of the most precious. The versatility of this material means that it is often used in wide-ranging uses, from ornamental decorations, jewelry and artwork to aerospace, machine/dentistry, electronics and currency. 1 Not all uses of gold req...

Resolving Difficult Interferences in Metallurgical Samples Sponsored by PerkinElmerFeb 18 2021 ICP-OES is frequently employed in the determination of trace elements in metallurgical matrices due to its ability to accommodate high levels of dissolved solids with no need to utilize matrix separation schemes or special sample introduction components. Because sample preparation does not require large dilution factors, analyte levels introduced to the instrument will not be significantly impacted by dilutions. Despite these notable benefits, spectral interferences may pose a partic...
