The field of X-ray fluorescence (XRF) spectroscopy is challenging and exciting. XRF was originally used to analyze geological samples. As the technique developed, with the advancements in computers and technology, XRF found its place in many different types of analytical laboratories. With advantages such as easy sample preparation, nondestructive rapid multi-element analysis, and the ability to screen unknowns in a wide array of sample matrices such as liquids, solids, slurries, powders, pastes, thin films, air filters, and many others; XRF offers a perfect complement to other types of analytical equipment found in the analytical lab. Because of these advantages the technique has a broad appeal to research, industrial, and quality assurance analysts.
XRF touches many aspects of our lives indirectly. It is used in the quality control of many products that we encounter daily. Determination of Fe content in milk powder and essential minerals found in vitamin tablets are examples of how XRF plays a role in our health. The ability to screen unknown samples in their raw form, aids in protecting us from hazardous chemicals, as well as identifying the elemental composition of evidence from a crime scene. Many other applications can be found in the applications section in more detail.
