I. What Is a Gold Purity Analyzer?

A gold purity analyzer is a device that uses X‑ray fluorescence (XRF) technology to analyze and determine the precise gold content—its fineness or purity—in a sample, as well as that of other precious metals such as silver and platinum, without destroying the sample. It enables rapid and reliable quality verification of gold products and is an essential instrument for enterprises in precious metals and jewelry.

II. Why Should Jewelry Shop Owners Use a Gold Purity Analyzer?

Compared to traditional methods, investing in a gold purity analyzer brings many practical benefits for jewelry shops:

Ensures transaction accuracy: Helps correctly identify the gold content in items, preventing confusion between different karats (24K, 18K, 14K, etc.).

Builds customer trust: Transparent verification increases credibility and professionalism.

Saves time and verification costs: Enables in‑house measurement quickly, speeding up order processing and reducing operational costs—no need to send samples out for external lab analysis.

Manages investment risk: A purity analyzer can detect fake or adulterated gold early, or items that do not meet required standards, thereby reducing risk when purchasing and ensuring a quality supply of gold.

III. Common Types of Gold Purity Analyzers

1. Handheld Spectrometer XL3t GOLDD+

The Thermo Scientific Niton XL3t GOLDD+ is a next‑generation handheld purity analyzer that incorporates the proprietary GOLDD™ technology, delivering superior performance in testing precious metals and alloys. Key features include:

• Measurement speed up to 10× faster, and accuracy up to 3× better, than conventional detectors.
• Non‑destructive analysis with near‑instant results.
• Capability to analyze up to 30 elements, ranging from magnesium (Mg) to uranium (U).

2. Tabletop Purity Analyzer DXL 800

The DXL 800 is a high‑end benchtop precious metal analyzer, essentially a “mini laboratory” with a single button. Its distinguishing features:

• Fast, non‑destructive analysis with results in just seconds.
• Accuracy comparable to the fire assay method, preventing losses from purchasing substandard or counterfeit inputs.
• Integrated AuDIT™ technology to detect gold plating and differentiate between real and fake gold.
• CCD camera to precisely locate the measurement area.
• Support for measuring 22 precious metal elements and trace elements that affect refining value.

3. Purity Analyzer SpectraX 25

SpectraX 25 is a benchtop device using energy‑dispersive XRF (EDXRF), specifically designed for jewelry workshops, gold & silver retail stores, testing centers, and precious metal recycling operations. Its features include:

• High‑performance SDD detector by Amptek (USA) with energy resolution of just 129 ± 5 eV, delivering fast and accurate results even for light elements.
• A 90° X‑ray beam path with specialized filters and two collimators (0.8 mm & 1.2 mm), optimizing stability for both small and complex samples.
• Capable of analyzing elements from sulfur (S) to uranium (U), particularly effective for gold‑silver, gold‑platinum, and palladium alloys.
• Detection of gold plating, metallic coatings, and trace alloying elements, enabling precise differentiation between genuine and fake gold.
• A measuring chamber size of 310 × 280 × 60 mm, suitable for both small jewelry and large items.
• User‑friendly software interface, multilingual support, optimized for user experience.

IV. Key Considerations When Purchasing a Gold Purity Analyzer

1. 1. Accuracy and Stability

When investing in a gold purity analyzer, accuracy and long‑term performance stability are of the utmost importance—especially for jewelry shops, jewelry retailers, and testing centers. Under the Vietnamese Standard TCVN 7055:2014, each gold fineness level is associated with an allowable error margin. (Note: Example citation format—adjust per actual source.)

Therefore, to ensure highly reliable analysis results, users should prioritize devices whose measurement error is less than or equal to half of the allowable error under TCVN—typically around ±0.01 to ±0.15.

Also, choose units that offer periodic calibration to maintain performance over time.

Non‑destructive XRF technology remains the industry standard for speed and precision in verifying gold, jewelry, and alloys.

2. Origin, Brand, and Certification

Favor devices from reputable brands widely used in the jewelry and precious metals industry: Thermo Scientific, Elvatech, Olympus, and so on.

Check that the machine holds proper quality certifications such as ISO 9001, CE, RoHS, which confirm international standards for safety and measurement accuracy.

Avoid machines of unknown origin, grey‑market imports, or smuggled goods: they often lack measurement reliability and are difficult or impossible to service.

3. Warranty, Technical Support, and After‑sales Service

A gold purity analyzer is a high‑technology device, so the manufacturer’s warranty should be a minimum of 12 months. Choose a supplier who offers:

• A well‑trained technical team with experience and access to standard reference materials compliant with both Vietnamese and international norms, enabling proper calibration and application tailored to your needs.
• Installation services and formal training for operators.
• Supply of genuine spare parts and periodic calibration as required.

4. Choosing a Reputable Vendor

Purchase from official distributors, legally registered companies with transparent and verifiable information. For online purchases, carefully check seller ratings, return policies, and request test videos showing the machine in real operation before making payment to ensure product quality.
