It is hard to tell if a gold-colored ring is made of genuine gold at first glance. However, analyzing the elements in the ring makes it quite easy.
The element is the smallest unit of which a substance consists. Perhaps you learned at school as a child that there are 90 elements in the physical world, from hydrogen (H) to uranium (U). Each element has its own unique attributes. When an element is exposed to an X-ray, just like in a medical check-up, it starts producing X-rays known as "fluorescent X-rays." Each element has a different degree of energy in its fluorescent X-rays. Therefore, It is possible to tell which element is which by measuring the energy level of a fluorescent X-ray. This is just like identifying people by listening to their voices.
An X-ray fluorescence element analyzer identifies the element by "listening to its voice." It takes only several tens of seconds to check the authenticity of a gold ring. Thanks to this characteristic, the device is widely used in various industries to confirm the quality of products or to research new substances. This technology is also contributing to the study of ancient cultures, as it allows instant analysis of the constituents of substances found at ancient ruins.
