Learn how gold tester and XRF analyzer work from the video below
X-ray Fluorescence (XRF) is a powerful, non-destructive analytical technique used to determine the elemental composition of materials. The process begins when an XRF analyzer, typically equipped with an X-ray tube, generates and directs primary X-rays onto the sample. As these high-energy primary X-rays interact with the atoms within the sample, they excite and eject inner-shell electrons. To return to a stable state, electrons from higher energy shells "drop down" to fill these vacancies, releasing excess energy in the form of secondary, or fluorescent, X-rays. Crucially, the energy emitted by these fluorescent X-rays is unique and characteristic to the specific element from which they originated, essentially acting as an elemental "fingerprint." A specialized detector within the XRF analyzer then measures the energy and intensity of these emitted fluorescent X-rays. Finally, the instrument's sophisticated software interprets this data, identifying the distinct energies to determine which elements are present (qualitative analysis) and measuring their intensities to quantify their concentrations (quantitative analysis), all without causing any damage to the sample.
Gold purity testing employs various tools and methods, ranging from traditional techniques to advanced non-destructive analysis.
X-ray Fluorescence (XRF) Analysis: This is the leading modern, non-destructive method. XRF Spectrometers / Gold Testers (like VRAY's XRF Analyzers) direct X-rays at the gold sample. The excited atoms then emit unique fluorescent X-rays, which the detector measures. The instrument’s software identifies all elements and quantifies their percentage (karatage, e.g., 0.05% for 9999 gold), providing rapid, precise results without damaging the sample. This method is indispensable for jewelers, refiners, and pawnshops.
Electronic Gold Testers: These are portable handheld devices that use electrochemical or electrical conductivity principles. A small drop of liquid or direct contact is made with the gold, and the device quickly indicates the approximate karat based on the electrical response.
