FAQs – Frequently Asked Questions

Here are 5 key technical specs to understand:

1. Detector:

Proportional Counter: Low cost, limited detection, meets basic needs.
Si-Pin: Great value, good precision for most needs.
SDD/Fast SDD: Ideal for high sample volume and faster testing.

2. X-ray Tube & Collimator:

Independent tube: Avoids overheating issues.
Collimator size: Choose based on sample type (0.5-2mm).

3. Mounting Type:

Top-down: Requires more care, suitable for large/sharp objects.
Bottom-up: More common, easier to use.

4. Calculation Method – FP Vs Empirical

• FP Method: uses formulas and physics to give you accurate results, even if you don’t have many samples to compare it with. 
• Empirical method compares your sample to known reference samples to figure out its composition.

Choosing the right Maxsell model depends on your industry, the volume of testing, and the level of accuracy you need. Below is a simple table to help you find the perfect fit for your business.

Water-based testers (densimeters) and chemical kits may look affordable but often give unreliable results:

• Densimeters only compare weight in air vs. water. If jewellery has stones, hollow, solder, or design variations, readings vary wildly.

• Chemical testers can scratch or stain jewellery and provide only rough estimates.

XRF machines, on the other hand, analyse the actual metal composition. This ensures:

• Accurate and consistent results across plain, studded, or mixed alloys.

• Non-destructive testing with no damage to jewellery.

• Professional reports that build trust with customers.

Quick Comparison – Water/Chemical Testers Vs XRF Gold Tester 

👉 Takeaway: Cheap testers save money upfront but risk wrong valuations and lost trust. XRF is the only reliable, long-term choice.

The difference between GPC, Si-PIN, and SDD detectors lies in how accurately and quickly they read gold purity — and which type of buyer they best fit.

💡 Quick Guide:

• Retailers / Loan Shops → Si-PIN

• Hallmarking & Manufacturers → SDD

• Just basic entry check → GPC

XRF machines can test jewellery without melting, but accuracy depends on how uniform the jewellery is.

• If the gold content is even throughout → the result is reliable.

• If there are solders, plating, or mixed designs → results may vary since XRF checks surface composition.

Retailer’s Action Plan:

• Test multiple spots on the jewellery.

• If readings are consistent, share it as the result.

• If readings differ, explain to the customer that only melting gives 100% certainty.

• Offer to melt in front of the customer (with consent) to build transparency.

✅ Do’s & ❌ Don’ts

👉 Quick takeaway:
XRF is accurate enough for uniform jewellery without melting. But when results vary, only melting ensures 100% accuracy. Being transparent in front of the customer helps you win trust and repeat business.

XRF machines don’t have high daily running costs. Most expenses come from periodic servicing and consumables, which are far lower than traditional testing methods.

Quick Takeaways

• No hidden running costs beyond power.

• Annual service costs are predictable (like a car checkup).

• Major components are designed to last years, not months.

• AMC (Annual Maintenance Contract) gives peace of mind and keeps costs controlled.

Action for Buyer: Always ask for the service contract details before purchase. Knowing AMC terms helps you estimate 5–7 years of ownership cost clearly. Maxsell’s long term policy is to keep the maintenance / service cost lowest and customer friendly. 

When an XRF machine detects an unknown metal or impurity, it does not mistakenly count it as gold. Every metal has its own spectrum, so the device identifies it separately.

However, if the impurity is not recognized (for example, in very low-cost or limited models), there can be small deviations in the gold percentage shown. This doesn’t mean the impurity is “added to gold,” but it can create confusion in the reading.

👉 That’s why choosing an “all-metal” XRF model is important. These machines can detect and display nearly all elements present, ensuring gold purity is shown correctly without hidden errors.

Key Takeaways

• Unknown metals are not added as gold.

• Limited machines may show slight deviations.

• All-metal models solve this by reading and separating every element accurately.

• Action step: Ask your supplier if the XRF model detects all metals before you buy.

Yes. XRF machines can detect gold plating by penetrating the surface up to 10–15 microns (sometimes more). This helps identify whether jewellery is solid gold or just plated.

Plated vs Solid Gold — How XRF Shows the Difference

XRF gold testers are highly accurate and reliable for jewellery retail, loan, and trade businesses. They provide precise results in seconds without melting the jewellery.

For official certification, fire assay is still the standard – but for daily business, XRF is the trusted choice worldwide.

Pro tip: Always test multiple spots on jewellery to confirm uniformity.

XRF accuracy comes from a combination of hardware, software, and usage practices:

Quick takeaway: Calibrated machine + proper usage = results you can trust.
