I. What Is a Metal Composition Analyzer?

A metal composition analyzer is a specialized device designed to accurately determine the proportion of elements present in a metal or alloy sample.
It can quickly test a wide range of metals such as gold, silver, platinum, copper, nickel, steel, aluminum, titanium, and others.

Thanks to its high accuracy and versatility, the metal analyzer has become an indispensable tool in industries that demand precision and efficiency.

II. Basic Working Principles of Metal Analyzers

Depending on the technology applied, each type of analyzer has its own unique mechanism.
However, in general, all analyzers work based on the principle of using an energy source (such as X-rays, plasma, or electric arc) to excite the atoms in the sample, causing them to emit characteristic signals.
The optical system and detectors of the device then collect and analyze these signals to determine the elemental composition of the sample.

Below are the three most commonly used technologies today:

1. OES Technology (Optical Emission Spectroscopy)

OES analyzers operate by exciting the metal sample with an electric arc or spark.
When excited, the atoms in the sample emit light radiation at specific wavelengths unique to each element.
By measuring the emitted light, the analyzer can identify and quantify the elements present.

OES is commonly used in metal production and quality control laboratories because of its speed and high accuracy when testing solid metal samples.

2. XRF Technology (X-ray Fluorescence)

The X-ray fluorescence (XRF) analyzer is the most widely used device in the jewelry and precious metals sector.
It directs a beam of X-rays onto the sample, causing atoms to emit secondary radiation (fluorescent X-rays).
The analyzer detects this fluorescence and determines the elemental composition based on the characteristic energy of the emitted rays.

XRF technology is used to identify metal types, measure gold purity (karat), and detect adulteration or alloying.
This technology is non-destructive, delivers results within seconds, and is user-friendly, making it ideal for jewelry shops and metal traders.

3. ICP Technology (Inductively Coupled Plasma)

The ICP analyzer uses a high-frequency inductively coupled plasma to ionize the sample (usually in liquid form).
Once ionized, the atoms emit light spectra that are unique to each element.
The analyzer reads these spectra to determine trace element composition with extremely high precision.

ICP technology is commonly found in research laboratories, universities, and industrial quality control centers where detailed quantitative analysis is required.
