The Niton XRF analyser, specifically designed for the gold market, has become a popular choice among gold buyers, jewellers, and other industry professionals due to its accuracy, speed, and non-invasive nature.

Purpose: accurate carat content identification in gold

The primary purpose of Gold Niton XRF technology is to provide accurate carat content identification in gold items. Assessing the purity of gold is crucial for determining its value, and hence, a reliable and precise method is necessary for fair and transparent transactions. Gold Niton XRF technology ensures that the gold’s carat content is accurately identified, which in turn helps gold buyers, jewellers, and other industry professionals to make well-informed decisions regarding the value of gold items. This accurate assessment of gold purity fosters trust between the buyer and seller, ensuring a fair valuation and a seamless transaction process.

II. How Gold Niton XRF Works

A. X-ray Fluorescence (XRF) Principle

  1. 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.
  2. 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.
  3. 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.

B. Non-destructive Analysis of Gold Items

  1. Preservation of gold items a. No physical damage: The Gold Niton XRF testing method does not require any physical contact with the gold item, preserving its original condition. b.
