Hand-held X-Ray Fluorescence (XRF)
Hand-held X-Ray Fluorescence is a portable analytical technique derived from the instrumentation used in traditional lab-based XRF analysis. The technique is used for bulk chemical analysis of rock, mineral, and sediment samples in the field. The technique depends on the fundamental principles of x-ray interactions with solid materials, similar to XRD analysis. XRF analysis is one of the most commonly used techniques for major and trace element analysis, due to the relative ease and low cost of sample preparation.
- X-ray fluorescence (XRF) is the emission of characteristic "secondary" (or fluorescent) X-rays from a material that has been excited by bombarding with high-energy X-rays or gamma rays. The phenomenon is widely used for elemental analysis and chemical analysis, particularly in the investigation of metals, glass, ceramics and building materials, and for research in geochemistry, forensic science, archaeology and art objects such as paintings and murals.
