In the gold and jewelry business, trust and transparency are the keys to success. Customers today demand accurate testing of gold purity, while counterfeit and low-karat gold are becoming increasingly sophisticated. That’s why many jewelry stores are now investing in XRF analyzers for gold testing – a reliable solution to ensure transparency, minimize risks, and build customer confidence.
I. What is an XRF Analyzer?
Basic structure of an XRF analyzer
1. Overview of XRF Analyzer
An XRF Analyzer is an analytical device that determines the elemental composition of a material using X-ray fluorescence. In the jewelry industry, XRF analyzers are considered the most advanced method to test gold purity and alloy composition.
With an XRF analyzer, jewelers can quickly verify the karat of gold, silver, or platinum in just a few seconds – without damaging the item.
2. How an XRF Analyzer Works
When X-rays strike a sample, its atoms emit unique fluorescent signals. The XRF analyzer detects these signals, compares them with a reference database, and instantly provides accurate results on the sample’s elemental composition.
Most importantly, the process is non-destructive – whether testing gold bars, rings, or chains, the jewelry remains intact after analysis.
II. Applications of XRF Analyzers in Jewelry Stores
1. Accurate Gold & Silver Purity Testing
Purity directly determines the value of precious metals. XRF machines identify the exact percentage of gold (10K, 14K, 18K, 24K, etc.) and other alloying metals. This allows jewelers to buy and sell with confidence and set fair prices.

2. Fast Authentication of Real vs. Fake Gold
Counterfeit gold, gold-plated jewelry, or under-karat items are common in the market. Traditional methods like acid testing are not only inaccurate but may also damage samples. With an XRF analyzer, jewelers can detect fake gold instantly – protecting their reputation and customers.
III. Why Every Jewelry Store Needs an XRF Analyzer?
Testing results from an XRF analyzer
1. Build Customer Trust
In the jewelry business, reputation is the most valuable asset. With an XRF analyzer, customers gain confidence knowing that every transaction is verified transparently, with clear scientific results rather than subjective judgment.
2. Avoid Risks of Fake or Under-Karat Gold
Just one mistake in purchasing low-quality gold can cost a jewelry store hundreds of millions of VND. An XRF machine accurately detects and eliminates such risks, helping store owners protect profits and avoid losses.
3. Save Time and Reduce Costs
In the past, many stores had to send samples to external testing centers, which was both costly and time-consuming. With an XRF analyzer, results are delivered on-site within seconds, enabling faster, more professional transactions while minimizing testing expenses.

IV. Popular Types of XRF Analyzers
Popular XRF analyzer models
1. Handheld XRF Analyzers – Portable & Convenient
Compact and easy to use, handheld XRF devices are ideal for small and medium jewelry shops. Testing can be done directly at the counter in seconds. Popular models include:
- Niton XL2 100G – suited for recycling and quality control.
- Niton XL3t GOLDD+ – detects restricted substances in consumer goods.
- Niton XL5 Plus – the lightest handheld XRF analyzer, with ultra-fast results.

2. Benchtop XRF Analyzers – High Precision & Professional
Equipped with advanced detectors and software, benchtop models deliver higher accuracy. They are perfect for jewelry chains or certification labs, and can also analyze a wide range of alloys beyond gold and silver.
V. FAQs About XRF Machines
1. Can XRF analyzers give incorrect results?
They are highly accurate, with a margin of error as low as ±0.1%. However, dirty or scratched samples, gold with plating layers, or thickly coated fake jewelry can affect results. Advanced models with AuDIT technology (e.g., Thermo Scientific XRF) can detect such cases.
2. Are XRF machines safe?
Yes. XRF analyzers use low-energy X-rays and come with built-in shielding for operator and customer safety.
3. Do XRF Analyzers require frequent calibration?
XRF analyzers come preloaded by the manufacturer with suitable analytical applications. At PMAC, when delivering the machine to customers, our technicians perform the initial calibration and provide annual checkups to ensure long-term accuracy.
In addition, the XRF models supplied by PMAC are equipped with certified reference standards for precious alloys specifically designed for the jewelry industry. We also customize applications based on customers’ unique requirements while ensuring compliance with both the Vietnamese and international jewelry markets. This significantly enhances the ability to detect filler elements often mixed into gold jewelry, such as Tungsten (W), Ruthenium (Rh), Osmium (Os), and Iridium (Ir).
