Make More Confident Precious Metals Buying Decisions

When you're buying gold, jewelry, coins, scrap, or other precious metals, knowing what you're actually buying matters. A mistake on a high-value item can quickly cost more than the price of an XRF rental.

The Thermo Scientific Niton DXL is a professional benchtop XRF analyzer designed specifically for precious metals testing. It provides fast, non-destructive elemental analysis to help gold buyers, jewelers, pawn shops, refiners, and precious metals dealers verify material before making important buying, sorting, and valuation decisions.

Rent a Niton DXL from Alloy Geek and add professional XRF testing capability to your business without purchasing an analyzer.

Best for

• Gold and precious metals buyers
• Jewelry stores and jewelers
• Pawn shops
• Coin and bullion dealers
• Precious metals refiners
• Estate jewelry evaluation
• Scrap gold and precious metals dealers
• Businesses that need temporary XRF testing capabilityTest Gold, Silver, Platinum & More

Verify before you buy

Verify before you buyHallmarks, visual inspection, magnets, density testing, and traditional gold testing methods can all provide useful information—but professional precious metals buyers often want another layer of verification.

The Niton DXL uses X-ray fluorescence (XRF) to measure the elemental composition of the tested area and provide results in seconds.

Use the DXL to:

• Verify gold purity and karat
• Analyze silver and silver alloys
• Analyze platinum and other precious metals
• Check jewelry before purchasing
• Evaluate precious metals inventory
• Identify unexpected alloying elements
• Investigate questionable or unusual material
• Screen for potentially plated or layered items
• Sort precious metal scrap
• Support buying and valuation decisions

Fast, Non-Destructive Precious Metals Analysis

Traditional testing methods can require acids, filing, scratching, or other contact with the item being evaluated.

XRF analysis is non-destructive.

Simply place the item inside the DXL's enclosed sample chamber, position the area you want to analyze, and perform the test. The analyzer measures the elemental composition of the tested area without cutting, grinding, scratching, or consuming the sample.

This makes XRF particularly useful when evaluating finished jewelry, collectible items, valuable pieces, and other materials where unnecessary damage should be avoided.

Why rent instead of buy?

You don't necessarily need to own an XRF analyzer to benefit from one.

A rental gives your business temporary access to professional precious metals analysis without committing capital to purchasing equipment.

Consider renting a Niton DXL when:

• Purchasing or processing a large jewelry collection
• Evaluating an estate
• Handling an unusually high volume of precious metals
• Performing an inventory verification project
• Your existing XRF analyzer is being serviced or repaired
• You need additional temporary testing capacity
• You want to evaluate XRF before purchasing an analyzer
• You only need professional XRF testing periodically

When the project is finished, simply return the analyzer.

Built specifically for precious metals

The Niton DXL isn't simply a general-purpose XRF analyzer being used to test jewelry.

Thermo Scientific developed the DXL as a dedicated precious metals analyzer with an enclosed benchtop design that is particularly well suited to retail and commercial precious metals environments.

Its workstation-style configuration makes it a strong choice for businesses performing repeated testing throughout the day.

Applications include:

• Gold
• Silver
• Platinum
• Precious metals
• Jewelry
• Coins
• Bullion
• Precious Metals Scrap
• Estate items
• Incoming precious metals inventory

Know what XRF is telling you.

XRF is an extremely useful precious metals analysis technology, but understanding the result is important.

The Niton DXL analyzes the elemental composition of the surface and near-surface region being tested. A result from one location should not automatically be interpreted as proof that an entire item has identical composition throughout.

Plating, coatings, layered materials, solder joints, unusual geometry, and the location being tested can all affect results.

When evaluating suspicious or high-value material, testing multiple locations and using additional verification methods may be appropriate.

This is particularly important when using XRF to evaluate jewelry and other potentially plated or constructed items.

New to XRF?

You don't need to be an XRF expert to rent from Alloy Geek.

We specialize in XRF equipment and support the instruments we rent. If you have questions about operating the DXL, testing technique, or understanding what you're seeing in the results, Alloy Geek can help during your rental period.

Try XRF in your real world environment

If you're considering purchasing a precious metals analyzer, renting gives you an opportunity that a demonstration cannot.

Use the DXL in your own business or precious metals operation.

Test the materials you actually buy. Let the people who will use the analyzer operate it. See how often XRF changes or supports a buying decision. Determine whether the equipment earns a permanent place in your workflow.

If you decide you'd rather own an analyzer, Alloy Geek also offers pre-owned XRF equipment when available.

Important Testing Information

XRF measures elemental composition at and near the tested surface. Results may be influenced by plating, coatings, sample geometry, test location, construction, and other factors.

For high-value transactions or questionable materials, Alloy Geek recommends appropriate testing procedures and multiple methods of verification rather than relying exclusively on a single XRF measurement.

Need help choosing?

If you're not sure whether the Niton DXL is appropriate for what you're testing, contact Alloy Geek before renting.

Tell us what materials you're analyzing and what you're trying to accomplish. We'll help determine whether the DXL or another analyzer in our rental fleet is the better choice.
