  • Analysis of precious metals in jewelry

    Abstract For thousands of years, man learned the craft of making jewelry from gold. Gold is a noble metal which does not react with the air and has a shiny yellow color.Over the years, alloying of the gold was necessary to improve its properties since pure gold is too soft to be used for jewelry. Alloying of the gold is usually by low-cost metals such as copper, zinc, silver or nickel. ...

  • Analytical Methodology for the Characterization of Steels and Iron Alloys by Atomic Absorption Analysis

    The analysis of irons and steels has always been a very important job in the industrial and commercial environment. The grading of steels and iron alloys is critical to characterizing their respective strengths to corrosion and stress. There are also many protocols for the several hundred types of steels available. Fe is always the primary component, with elements such as Ni and Cr as major ...

  • New ways for Metal Recycling

    REWAVE XRF 3-way-sorting in innovative  “Free-Fall”-design Recycling of metal and aluminium knows no limits because it can be remelted as scrap indefinitely. Metals, however have to be separated from non-metallic impurities, and different metals have to be sorted in pure fractions to be used as secondary raw materials substituting primary resources. Especially when it ...

  • Hired metals analyser ensures remediation success

    Cognition Land and Water Ltd, a UK based remediation specialist, has hired a portable XRF metals analyser to improve the speed of remediation work at a project in London’s Kentish Town. The project had a major impact on local residents so timescales were extremely tight but Cognition’s Charlie Jarvis says “It would not have been possible to meet the deadline without the use of ...

  • Drosrite extensive on-site hot dross treatment tests

    DROSRITE is a salt-free process for the recovery of metal from dross. In addition to producing a salt-free residue, it does not produce any CO2 or NOx gases. The process is highly energy efficient, extracting heat from energy in the residue and, thus, it does not require an external heat source such as a plasma torch, an electric arc or a gas or oil burner. A DROSRITE pilot unit built by ...

  • Air crash investigation using Oxford Instruments handheld analysers - case study

    It was late April 1945 during the last days of World War II for Italy. Just one week before the liberation of Italy from the fascists rule, a group of five Messerschmitt BF 109 planes took off from the Vicenza airbase heading to Ghedi, near Brescia. This was not a combat mission but a transfer flight. Soon after take-off the planes were intercepted by US fighters and attacked. All five planes ...
