LONDON -- The National Physical Laboratory has launched a six-month study into the use of XRF techniques.

NPL said in a press release that 10 companies have already signed on to participate in the project, which will assess XRF as a means for determining the presence and amount of various hazardous substances.

The protocol would include assessing a range of sample configurations incorporating known issues with RoHS-prohibited contaminants. Samples would be chemically analyzed prior to round-robin testing. After testing, the actual samples used will be chemically analyzed again to eliminate batch variance problems. The final report would include a comparison of XRF techniques and test sites.

The project is scheduled to launch this month July and last six months. The work will be presented to the NPL Soldering Science & Technology Club and disseminated in an NPL Report.
