Lack of confidence makes NPL to study XRF testing

The National Physical Laboratory (NPL) is to study X-ray fluorescence (XRF) testing, the front line technique for testing for and spotting RoHS non-compliance since the technology “The reason behind this is lack of confidence when using this technique for RoHS,” project head Dr Chris Hunt told EW. The XRF testing is used to determine which elements are in a sample. “We will get a range of samples, and the partners will measure them with the different XRF instruments they own,” said Hunt. “Then we will use chemical analysis to see accurately what is in the samples.”
