II. How Gold Niton XRF Works
A. X-ray Fluorescence (XRF) Principle
- Fundamentals of X-ray fluorescence a. Excitation of atoms: When a gold item is exposed to X-rays, the atoms in the material become excited. b. Emission of secondary X-rays: The excited atoms return to their stable state by releasing secondary X-rays, known as fluorescence. c. Element-specific energy: Each element in the material emits X-rays at unique energy levels.
- Detection and analysis a. Collecting emitted X-rays: The Gold Niton XRF device captures the emitted secondary X-rays. b. Energy spectrum analysis: The device’s detector measures the energy levels of the captured X-rays, creating an energy spectrum. c. Identification of elements: The energy spectrum is analysed to identify the elements present in the material, based on their unique energy signatures.
- Quantitative analysis a. Intensity correlation: The intensity of the emitted X-rays is proportional to the concentration of the corresponding elements in the material. b. Calculation of concentration: The Gold Niton XRF device uses software algorithms to calculate the concentration of each element detected in the material.
