  • 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 ...

  • Using THz spectroscopy to analyse atomic layer deposited (ALD) TiN

    Oxford Instruments and das-nano demonstrate non-destructive wafer based thickness and resistivity metrology for PEALD TiN. Commonly titanium nitride (TiN) thickness and resistivity wafer fab in-line metrology is based on ellipsometry and 4-point probe resistivity mapping. Alternative and relatively slower or more complex methods are X-ray photoelectron spectroscopy (XPS), X-ray ...

  • Why LIBS means lower cost of ownership

    Laser Induced Breakdown Spectrometry (LIBS) and X-ray Fluorescence (XRF) handheld analysers are both compact, easy-to-use and fast. Materials can be identified at the pull of a trigger. It’s that simple. Often, cost is a key factor in the decision making process, especially when it comes to thinking about overheads long-term. When both products are comparably priced and have a similar ...

  • 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 ...

  • Using EDXRF to quantify the amount of Metals in Asphalt Binders

    This article reviews these sources and proposes a scheme for measuring and quantifying the amounts of metals in their source materials used to bind asphalt used in making roads. The use of bench top EDXRF to characterize binders before blending them into asphalt cements is possible because the metal values are in the 10s – 1000s of ppms and are readily monitored. ...
