Thermo Scientific Niton XL3t 700 handheld XRF analyzer for nondestructive elemental screening of non-human materials, configured with Metals, Metals Pass/Fail, Electronics Metals, Plastic, Consumer Goods, Painted Products, TestAll, and Spectral FingerPrint modes.
The Thermo Scientific Niton XL3t 700 is a handheld X-ray fluorescence (XRF) analyzer used for nondestructive elemental screening of non-human materials including metal alloys, electronic-component metals, polymer-based goods, and coated or painted products. The instrument uses mode-based workflows that align measurement setup and reporting to a material category and screening objective, supporting alloy identification tasks alongside consumer-products screening for restricted elements and toxic metals.
In consumer-products screening contexts, the XL3t 700 Series is described as providing screening of consumer goods for lead (Pb), cadmium (Cd), mercury (Hg), and other toxic metals. TestAll technology and Painted Products mode are described together for differentiating lead in a surface coating (paint/glaze) from lead in substrates such as plastic, metal, and wood, supporting more targeted screening when coatings may be present. Plastics screening in the XL3t platform is described with plastic-focused workflows that include toy and consumer-goods plastics screening contexts.
