  • 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 ...

  • Analyzing sulfur in soil and sediment with handheld XRF

    Background Sulfur creates more than nasty odors. Exposure to low levels (0-10ppm) of hydrogen sulfide (H2S) causes irritation of eyes, nose, and throat; higher levels can cause headaches, dizziness, nausea and vomiting, coughing, and breathing difficulty. H2S and numerous other odor-causing compounds are generated as a result of organic material decomposition. In the case of the Muddy River in ...

  • 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 ...

  • 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 ...

  • Handheld XRF analyzer, X-MET7000, for rapid, non-destructive Drywall testing – New application note from Oxford Instruments

    The handheld XRF analyzer - X-MET7000 - offers a rapid and non-destructive solution for screening of tainted and potentially hazardous Chinese drywall and for lead inspection. At the height of the U.S. housing boom, when building materials were in short supply, American construction companies used millions of pounds of imported drywall ...

  • Lead (Pb) in Workplace Air by Niton 700 Series Field Portable X-Ray Fluorescence (XRF) Analyzer

    Procedure: Air samples are collected by drawing workplace air, using personal sampling pumps, through 37-mm mixed cellulose ester (MCE) filters mounted in polystyrene cassettes. Samples are prepared for XRF analyses by transferring each filter, along with the support pad, to a special air filter sample holder, specifically designed for a Niton XRF analyzer. Three separate 60-second readings are ...

  • Lower costs, fewer delays - a highway expansion project applies XRF technology to obtain cost-effective remediation.

    X-ray fluorescence (XRF) spectrometry is a non-destructive, analytical method used primarily to detect the metal composition in soil/solids samples. Portable XRF instruments can provide rapid, accurate analysis of heavy metal levels in soil on new construction or redevelopment sites. In response to the growing need for field analysis of metals, many of these units have been adapted for use in the ...

  • 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 ...

  • Assessing natural contents of hazardous metals in soils by different analytical methods and its impact on environmental legislative measures

    A variety of analytical techniques are commonly used to assess natural metal concentrations in soils. Although the choice of the analytical procedure may appear to be an unimportant issue, through an example from the Po Plain we document that for specific hazardous metals the arbitrary choice between separate analytical techniques may have contrasting legislative implications. Comparative ...

  • Removal of heavy metals from aqueous solution by limestone

    This study focused on the removal of Pb(II), Cd(II), Cu(II), and Zn(II) using reagent solutions by natural limestone in a batch system. The sorbent, collected from the Late Cretaceous limestone beds, Tunisia, was characterised by X–ray diffraction (XRD), chemical analysis (XRF) and infrared spectroscopy (FTIR). XRF showed that the studied limestone contained high amount of calcium carbonates. XRD ...

  • Handheld X-Ray Fluorescence: Practical Application as a screening tool to detect the presence of environmentally-sensitive substances in electronic equipment

    Abstract: As the implementation deadlines approach, the electronics industry is focusing significant efforts on compliance with the Restriction of Hazardous Substances (RoHS) directive and the Waste Electrical and Electrical Equipment (WEEE) directive. The intent of the EU RoHS Directive (2002/95/EC) is to restrict the use of six substances (lead, mercury, cadmium, hexavalent chromium, PBBs and ...
