The commonly used instruments and principles of gold purity measurement

In the field of gold identification and testing, it is crucial to accurately measure the purity of gold.To achieve this goal, scientists have developed various instruments and technologies to help people test the purity of golden samples quickly and accurately.This article will introduce some commonly used instruments and principles to measure goldenness.

1. X -ray fluorescent analyzer

X -ray fluorescent analyzer is a instrument that is commonly used in measuring material composition and content, and is also widely used in the content of other impurities elements in golden samples.Its working principle is to generate X -rays by the surface of the sample, and analyze the X -ray energy spectrum based on different elements to determine the content of each element.

2. Flame method

The flame method is a traditional and effective method, which is usually used to quickly test small batch or low -value gold samples.This method uses a specific color flame to determine its ingredients when reacting with different chemical substances to the test sample.By observing the color of the flame, it can be preliminarily determined what impurities may exist in the sample.

3. Solid conductivity method

The solution guidance rate method uses the characteristics of ion in the solution to detect the characteristics of different current conductivity.When an electrolyte solution is formed after the test sample is dissolved, it can infer the type and content of impurities of impurities by detecting changes in the conductivity.

4. Valic metal probe

Valic metal probe is a device specially designed for fast, non -destructive inspection of jewelery and other products.

In addition, in the actual application process, it is necessary to coordinate with each other in conjunction with multiple methods to obtain more accurate and reliable results.
