Discover how advanced technologies like XRF, LIBS, and AuDIT change how we analyze materials. These technologies empower our analyzers to examine objects to help uncover what they are made of, down to the elements. Each technique offers unique insights to support accurate, reliable measurements, from identifying elemental compositions to detecting gold plating.
X-ray fluorescence spectroscopy (XRF) is a non-destructive analytical technique used to determine the elemental composition of materials. XRF analyzers measure the fluorescent (or secondary) X-rays emitted atoms contained in a sample when excited by a primary X-ray source. Each element present in a sample produces a set of characteristic fluorescent X-rays, or “unique fingerprints.” These fingerprints are distinct for each element, making XRF analysis an excellent tool for quantitative and qualitative measurements of materials.
Laser-induced breakdown spectroscopy (LIBS) is an analytical technique used to determine the elemental composition of materials. Handheld LIBS analyzers work by using a highly focused laser to ablate the surface of a sample. A plasma is formed consisting of electronically excited atoms and ions. As these atoms decay back into their ground states, they emit characteristic wavelengths of light. These wavelengths are distinct for each element, making handheld LIBS analysis an excellent tool for quantitative analysis of carbon and alloying elements in steel and stainless steel.
Our proprietary and patented Thermo Scientific AuDIT gold-plating detection technology includes several independent, complementary algorithms. These work together to alert you to the probability that an item is plated, regardless of the gold concentration of the surface layer.
AuDIT software alerts you when gold plating of up to 8µm is detected or suspected, warns you on low karat and non-standard karat measurement, and identifies the presence of nickel (Ni) often used underneath gold plating. While limited to the thickness of gold typically used in jewelry and industry for plating items, the AuDIT technology detects plating on any non-gold substrate, such as Vermeil (gold-plated silver), copper alloys, steel, tungsten, and others.
