1. I. Definition of a Gold Analyzer

1. 1. What Is a Gold Analyzer?

A gold analyzer is a specialized device designed to determine the karatage (purity) and gold content in a sample. Additionally, these instruments can detect the presence of various alloys and other precious metals such as silver, platinum, and palladium. Gold analyzers are widely used in jewelry shops, precious metal trading, and small to medium-sized manufacturing businesses.

2. 2. How Does a Gold Analyzer Work?

Most modern gold analyzers operate using X-ray fluorescence (XRF) technology. When the device directs X-rays onto a gold sample, atoms within the material emit secondary (fluorescent) X-rays that are unique to each element. The analyzer detects and interprets these signals to determine the percentage composition of each metal present. This process is rapid, accurate, and completely non-destructive.

2. II. Why the DXL 800 Is the Leading Choice for Jewelers?

The DXL 800 by Thermo Scientific (USA) is a trusted, all-in-one solution for jewelers, assay offices, and manufacturers, enabling fast and highly accurate gold testing without damaging the sample.

Whether you operate a traditional gold shop, a gold-buying business, or a large-scale jewelry production facility, the DXL 800 enhances operational efficiency with speed, precision, professionalism, and elevated credibility with clients.

3. III. Key Advantages of the DXL 800 Gold Analyzer

Figure 2: Technical Specifications of the Gold Analyzer

1. 1. Delivers Fast, Highly Accurate, Non-Destructive Results

The DXL 800 by Thermo Fisher utilizes advanced X-ray fluorescence (XRF) technology, enabling rapid and precise gold content analysis within seconds.

It offers a faster and simpler alternative to traditional fire assay or nitric acid testing methods, without altering the sample’s physical state.

The exclusive AuDIT™ technology by Thermo Scientific ensures accurate differentiation between solid gold and gold-plated items.

2. 2. User-Friendly, Compact, and More Flexible Than Traditional Methods

The DXL 800 features an intuitive touchscreen interface and simple operation (place sample – close lid – press button), minimizing the need for highly trained technical staff.

As a compact benchtop "mini-lab," the DXL 800 is elegantly designed and suitable for use in:

• - Large and small jewelry counters

• - In-house quality control laboratories

• - Mobile gold-buying stations or inspection rooms within jewelry or component manufacturing facilities

3. 3. Safe for Users

The DXL 800 is engineered with a fully enclosed analysis chamber to minimize X-ray exposure to the external environment.

Additionally, LED lighting systems at the front and rear of the chamber allow both jewelers and customers to observe the sample in real time throughout the testing process—without the need for any hazardous chemicals or strong acids that could cause burns, damage clothing, or corrode work surfaces.

4. IV. Applications of Gold Analyzers in Jewelry Operations

1. 1. Verifying Quality of Incoming Raw Materials

Gold analyzers play a vital role in verifying the purity of incoming materials by detecting not only pure gold (Au) but also alloying elements like silver (Ag), copper (Cu), nickel (Ni), and zinc (Zn).

For example, the DXL 800 enables quick classification of gold purity by karat (24K, 18K, 14K, etc.)—ensuring consistency, minimizing classification errors, and maintaining product quality standards.

2. 2. Karat Determination During Purchasing and Reselling

In gold trading, errors in karatage during buying or selling can lead to financial losses, pricing disputes, and damaged partnerships.

Whether working with customers, artisans, or suppliers, the DXL 800 ensures accurate valuation of gold, protects profit margins, and helps establish transparency and fairness in every transaction.

3. 3. Quality Assurance Before Product Release

Even the smallest oversight in gold content verification can lead to returned goods, brand damage, or customer disputes.

Using the DXL 800 to re-check gold purity before shipping out products not only reduces risk but also reinforces a brand’s commitment to quality and transparency—a key advantage in long-term client relationships.

4. 4. Detecting Fake or Plated Gold

As counterfeit gold becomes increasingly sophisticated, relying on visual inspection or traditional testing methods is no longer sufficient.

The DXL 800, with XRF technology and AuDIT™ algorithm, can automatically detect gold plating, impurities, and under-karat items, helping to prevent fraud and strengthen your brand’s integrity.

5. 5. Used in Assay Centers and Certification Facilities

For assay offices and certification centers, a high-precision analyzer like the DXL 800 is indispensable. It provides fast, accurate, and non-destructive analysis of gold content, forming the basis for issuing karatage certificates—critical documents for retail, export, or display purposes.

Using certified equipment enhances regulatory compliance, brand reputation, and market value of certified jewelry.
