Some manufacturers have been screening products for lead using hand-held x-ray fluorescence units, though the CPSC has not allowed such instruments to be used for the certification of products to the lead paint standard because they are not sensitive enough to produce reliable quantitative results at regulated levels. In fact, the CPSC's staff report clearly states that "XRF methods other than those specified in ASTM F2853-10 are not considered effective for testing lead in paint and surface coatings for the purpose of conformity with 16 C.F.R. part 1303 at this time."
By contrast, XOS HDXRF instruments use next generation technology and are sufficiently precise and reliable to measure lead in paint well below the current limit of 90 parts per million. In addition, HDXRF is highly precise at quantifying even low levels of lead in a variety of substrates including plastics, metals and glass. XOS analyzers are also easy to operate, involve no sample preparation, and require only minutes of testing time.
Satbir Nayar, XOS Product Manager, notes, "Not only is the CPSC using an HDXRF analyzer in their lab, but more test laboratories, retailers and manufacturers are turning to these analyzers for their ease of use and detection performance to ensure products are safe and compliant." XOS instruments are also capable of not only simultaneously measuring the lead in paint and substrate materials (and giving accurate measurements for both), but they can also precisely measure cadmium, arsenic, mercury, antimony, and other elements that may be of concern in consumer products.
