The history of X-rays goes back to 1895, when Wilhelm Conrad Roentgen discovered and identified X-rays. Then, in 1909, Charles Glover Barkla discovered a connection between X-rays radiating from a sample and the atomic weight of the sample.
Nondestructive testing (NDT) provides the ability to monitor various aspects of material and product quality without compromising part integrity. Many NDT technologies can be applied to ensure proper manufacturing and functionality.
Modern XRF has become a common analytical instrument technique for the quality assurance of manufactured products, including out-going product verification and production quality control as well as incoming inspection.
