X-ray fluorescence is an analytical technique in which X-rays are used to excite tightly held photoelectrons in the atoms that make up a material. The Bruker Tracer III XRF allows staff to do rapid, non-invasive element identification, from magnesium (Mg) to uranium (U). Because it is a portable instrument, it can be used on a wide range of materials without any sampling, and makes this instrument highly versatile for examination of collection materials in curatorial spaces.
Applications:
- identification of gold, mercury, and other metals used as photographic toners; useful for dating and guiding treatment decisions
- screening of collection materials for suspected insecticides such as arsenic
- inorganic pigment or ink identification
