    XRF Equipment as a RoHS Screening Tool
    A jointly funded industry/DTI collaborative project, led by the National Physical Laboratory, investigated the suitability of XRF techniques for determining the presence and levels of RoHS-restricted substances in typical electronics components. The 15-system study found most – but not all – are viable.
