Description
The Evident Vanta GX-LT is an affordable benchtop XRF analyzer designed for fast, nondestructive analysis of gold, jewelry, coins, silver, platinum, palladium, and other precious metals. Featuring a high-resolution silicon drift detector (SDD), integrated touchscreen, built-in camera, and enclosed sample chamber, the Vanta GX-LT provides precious metal composition and purity results in seconds.
Designed for jewelry stores, pawn shops, gold buyers, precious metal dealers, coin dealers, and other businesses that regularly evaluate valuable metal items, the Vanta GX-LT provides a simple alternative to traditional acid testing while leaving the item being tested intact.
Precious Metal Testing Applications
The Vanta GX-LT is designed for routine precious metal analysis where fast, reliable results are needed to support buying, selling, pricing, and verification decisions.
Gold & Jewelry Testing
Quickly determine the composition and purity of gold jewelry, scrap gold, rings, necklaces, bracelets, watches, and other valuables. The Vanta GX displays elemental chemistry and gold karat information directly on its integrated touchscreen.
A built-in gold plating alert helps identify plated items that could otherwise be mistaken for solid precious metal.
Pawn Shops & Gold Buyers
For businesses purchasing precious metals directly from customers, the GX-LT provides actionable results while the transaction is taking place.
Operators can quickly verify precious metal content, evaluate an item's composition, and use the resulting chemistry to support purchasing and pricing decisions. Testing is nondestructive, so valuable customer property does not need to be scratched, cut, or chemically altered.
Jewelry Stores
The compact benchtop design makes the Vanta GX-LT suitable for integration directly into a jewelry store or showroom.
Results can be displayed on the analyzer's touchscreen or presented on a larger screen to help explain results to customers. The analyzer's built-in camera can pair an image of the item with its test results for improved documentation.
Coins, Bullion & Precious Metal Valuables
Use the Vanta GX-LT to evaluate the elemental composition of coins, bullion, and other precious-metal valuables without damaging the item.
XRF provides elemental chemistry rather than relying solely on visual inspection, markings, or traditional acid scratch testing.
Silver, Platinum & Palladium
The Vanta GX platform isn't limited to gold. It can determine the purity of silver, platinum, palladium, and other precious metals in seconds, making the GX-LT useful for businesses handling a variety of precious-metal products.
Lead & Cadmium Screening in Jewelry
In addition to precious metal composition, the Vanta GX can detect potentially hazardous elements including lead (Pb) and cadmium (Cd) in jewelry.
Fast, Nondestructive XRF Analysis
Testing with the Vanta GX-LT requires no routine sample preparation or acid handling. Place the item inside the shielded sample chamber, close the lid, and initiate the test.
Results appear directly on the full-color touchscreen, allowing operators to quickly obtain elemental composition and precious metal information.
The Vanta GX can provide detection of up to 27 elements and includes alerts for gold plating and hazardous elements, providing considerably more information than simply determining whether an item contains gold.

Vanta GX-LT vs. Vanta GX-LTS
The Vanta GX is available in two configurations. The GX-LT is designed as the affordable option for routine precious metal testing, while the GX-LTS is the premium model for higher-throughput testing, increased precision, and complex jewelry analysis.
| Feature | Vanta GX-LT | Vanta GX-LTS |
|---|---|---|
| Positioning | Affordable precious metal analysis | Premium precious metal analysis |
| Detector | SDD | SDD |
| X-ray Tube | 2 watt | 4 watt |
| Maximum Voltage | 35 kV | 40 kV |
| Maximum Current | 50 µA | 200 µA |
| Standard Spot | 9 mm | 9 mm |
| Small Spot | — | 3 mm |
| Fine Spot | — | 1 mm |
| Precision | Standard | High |
| Test Speed | Short test times | Shorter test times / higher throughput |
| Best Suited For | Routine gold and precious metal testing | Complex jewelry, small features and higher-throughput testing |
Evident specifically positions the GX-LTS for reliable high-throughput analysis of gold and other precious metals, including complex jewelry, while the GX-LT provides reliable analysis with standard precision and a 9 mm measurement spot.
Which Vanta GX Should I Choose?
Choose the Vanta GX-LT when your primary application is routine analysis of jewelry, gold, silver, coins, bullion, scrap, and other precious-metal items that can be effectively measured with the standard 9 mm XRF spot.
Consider upgrading to the Vanta GX-LTS when you regularly analyze small or complex jewelry features, need a smaller measurement area, or have enough testing volume to benefit from the LTS model's higher-powered X-ray tube and shorter test times.
The GX-LTS provides selectable 9 mm, 3 mm, and 1 mm spots, enabling much more targeted measurements of small features than the GX-LT's standard 9 mm spot.
