The Thermo Scientific Niton XL3t Series handheld x-ray fluorescence analyzer from Thermo Fisher Scientific has geometrically optimized large area drift detector technology, which delivers improvements in light element detection, overall sensitivity, and measurement times up to 10 times faster than conventional Si-PIN detectors, and up to three times more precise than conventional smaller, silicon drift detectors. It provides immediate, nondestructive chemical analysis of aluminum, titanium, and nickel alloys, as well as superalloys, stainless steel, and other alloys. Light elements such as magnesium, aluminum, silicon, phosphorus, and sulfur can be analyzed without helium or vacuum purging.The analyzer incorporates 80 MHz real-time digital signal processing and dual embedded processors for computation, data storage, live video processing, and communication. Users can isolate small areas on a sample using the CamShot integrated color CCD camera and optional WeldSpot integrated 3-mm small-spot focus feature, and then store the image of the area. This feature is suited for isolation and analysis of weldments separate from the joined components to verify proper dilution rate.
