  • Properties of self-assembled Ge islands grown by molecular beam epitaxy

    Self-assembled germanium islands have been grown on Si (001) substrates using solid source molecular beam epitaxy. A series of annealing experiments have been performed at a temperature 650°C in order to clarify some issues related to island stability and coarsening mechanism. The shape and size distribution of Ge islands as a function of annealing time up to 90 min have been studied through ...

  • Vulcan case study, future proofing a scrap yard - Case Study

    “Quality second generation analyser that is well built, robust and fast. Perfect for what we need in the scrap yard.” As a start-up scrap yard, Romuta wanted to build an advanced, digitalised scrap yard of the future. They met with Hitachi High-Tech Analytical Science team to test the Vulcan laser induced breakdown (LIBS) analyser, being impressed with its speed in accurately ...

  • Trust your supplier, but also check

    In the wake of mis-certification scandals around the world, firms are tightening their quality assurance (QA) processes using materials analysers.Industry has been shaken recently by news of companies providing false certification in a range of fields, from emissions testing through to metal grading. Cases where suppliers have delivered mislabelled products only serve to highlight the importance ...

  • Why accurate analysis holds the key to your future

    Nostalgia can be deceptive. Things always seem to have been better “back in the day”. The truth is, many basic materials were of a superior quality in the 1970s. As the decades have progressed, production techniques and competition have driven down the price of many materials including steel in real terms. And it seems the quality has followed. However, not all is lost. You just need ...

  • Why detection limits matter in metals quality control

    The new Hitachi OE750 spark spectrometer can measure the entire spectrum of elements in metals to low detection limits. For us at Hitachi High-Tech, this was the goal for the OE750 development team and why we ended up designing a completely new optical concept and using a different detector technology. Our view is that detection limits of below 10ppm or >1 ppm (depending on the application and ...

  • On-site elemental analysis of drywall with the Thermo Scientific Niton XL3t series XRF analyzer

    Application Reports of headaches, nosebleeds, central nervous system disorders, and other serious health effects have been reported from those exposed to compounds emitted from Chinese drywall (CDW). Additionally, surface corrosion of metal objects, including jewelry, decorative plumbing fixtures, HVAC coils, and electrical wires have resulted in cosmetic and mechanical damages. These ...

  • The application of radiation sources in the oil and gas industry and shortages in their services

    Oil and gas industries utilise many radiation sources in various applied radiation-based technologies. Those technologies provide significant benefit to the daily operations of the industry. Gamma emitting sources of Cs-137, Co-60, Ba-133, Am-241 are used in oil and gas well logging, in Multiphase Flow Meter (MPFM) technology at oil and gas production facilities and in transmitted level gauges ...

  • What is Laser Induced Breakdown Spectroscopy (LIBS)?

    Laser Induced Breakdown Spectroscopy or LIBS is an analytical technique that's been used in laboratories for many years.  Most handheld LIBS analysers are used for fast sorting of alloys in scrap yards, and alloy identification and analysis in various applications within the metals industry. ...

  • Sample preparation is the key to quality analysis with a laser analyser

    Sample preparation is the most important step of any chemical analysis. To get the best results with any elemental alloy analyser regardless of the technology, the sample must be clean before taking a measurement. Otherwise the results are always compromised at least to some extent. The effect of dirty surfaces will vary and some technologies are more forgiving to sample surface conditions than ...

  • Next-generation OES analysis for total metals control

    There’s never been a more demanding time for those in the metals industry. Foundries and steel plants are under increasing pressure to use scrap materials in the melt. Supply chains are getting more complex and perhaps less reliable. Legislation for trace elements is getting ever tougher. The result is that to be able to consistently produce a profitable, high quality product that meets all ...
