Key Technology of Compact XRF Spectrometer

The VRAY VR-X5 Compact XRF Spectrometer integrates several key technologies to deliver its performance:

1. X-ray Fluorescence (XRF) Principle: The core technology, where X-rays are used to excite atoms in the sample, causing them to emit characteristic secondary X-rays. The energy and intensity of these secondary X-rays are then analyzed to determine the elemental composition and concentration.

2. Customized Si-Pin Detector: This is the primary X-ray detector. A Silicon PIN diode detector offers good energy resolution, allowing for clear separation of characteristic X-ray peaks from different elements. "Customized" implies it's optimized for the specific application of precious metal analysis, balancing performance with the "compact" and cost-effective design.

3. Micro-Focused Tungsten Ray Tube (50W, 50 kV, 1mA): This is the X-ray source. A tungsten anode generates a broad spectrum of X-rays capable of exciting a wide range of elements found in gold and its alloys. The "micro-focused" aspect helps concentrate the X-ray beam for better spatial resolution, and the 50W power provides sufficient intensity for rapid and accurate analysis.

4. Collimator ($\varphi$2.5mm): The collimator is a critical component that shapes and directs the X-ray beam precisely onto the specific area of the sample being analyzed. The ϕ2.5mm size is well-suited for typical jewelry items and small gold samples.

5. Integrated Computer (Intel i5 3320M): The inclusion of an inbuilt Intel i5 3320M computer provides the processing power for data acquisition, spectral analysis, and result display. This integration simplifies the system, eliminating the need for an external computer and making it truly "all-in-one" and compact.

6. Efficient Heat Dissipation System: The dedicated T-shaped radiator is essential for managing the heat generated by the X-ray tube and other electronics. This system ensures stable operation and allows for continuous use without mandatory cool-down periods, which is vital for busy retail environments.

7. Proprietary Software and Algorithms: While not explicitly listed, any XRF spectrometer relies on sophisticated software algorithms to process the raw spectral data from the detector, identify elements, quantify their concentrations, and calculate karatage with the specified 0.05% accuracy for 9999 gold.

Price and ROI

The VRAY VR-X5 Compact XRF Spectrometer is priced between $10,000-$11,000, offering a compelling Return on Investment (ROI) for businesses involved in gold testing:

ROI for Retail Environments:

• Fraud Prevention (Immediate Impact): This is the most significant ROI factor. The spectrometer's 0.05% accuracy for 9999 gold and wide element range (K~U) instantly identifies fake gold, plated items, or highly adulterated alloys. Preventing even a few instances of accepting fraudulent or mis-karated gold, especially high-value items, can quickly cover the spectrometer's cost.

• Accurate Valuation (Increased Profitability): For jewelers and pawnshops, precise karatage and composition data mean buying at fair market value and setting accurate resale or loan values. This directly impacts profit margins by avoiding overpayments and ensuring competitive pricing.

• Enhanced Customer Trust & Transparency: Performing on-the-spot, non-destructive analysis in front of the customer builds immense credibility and trust. This transparency leads to repeat business and positive word-of-mouth, which is invaluable for retail success.

• Reduced Operational Costs: Eliminates the need for traditional, destructive acid tests, which can damage items and require consumables. It also reduces reliance on costly external assay services.

• Increased Efficiency and Throughput: The 40-second test time allows for rapid appraisals, speeding up customer interactions. The "no waiting for cooling" feature ensures continuous operation during peak hours, maximizing the number of transactions per day.

• Versatility in Testing: Being able to test solid, liquid, and powder samples broadens the types of items that can be accurately assessed, expanding business opportunities.

• Compact Footprint (Space Savings): The compact size means it integrates easily into existing retail spaces, avoiding the need for dedicated lab areas or large investments in new furniture.

Given its precision and efficiency, the VR-X5 can generate a positive ROI relatively quickly, often within months, by protecting against losses from fraud and enabling more accurate, profitable transactions.

How to Use

Using the VRAY VR-X5 Compact XRF Spectrometer is designed to be straightforward for quick and efficient gold testing in retail environments:

1. Power On: Plug the spectrometer into a standard electrical outlet and turn on the main power switch. Since it has an inbuilt Intel i5 3320M computer, the system will boot up directly.

2. Open Chamber: Open the secure sample chamber door. Safety interlocks prevent X-ray emission when the door is open.

3. Place Sample: Carefully place the gold item (e.g., ring, chain, coin) or other precious metal sample onto the designated sample stage inside the chamber. Ensure it is positioned under the X-ray window (usually marked by a circle or crosshair) for accurate analysis. The 270 x 260 x 100mm chamber size offers ample space.

4. Close Chamber: Close the sample chamber door firmly. The system will confirm the door is securely closed.

5. Select Test Mode: On the integrated computer's screen, select the appropriate test mode, usually "Gold Karatage," "Precious Metals," or a specific alloy analysis depending on the software interface.

6. Initiate Test: Press the "Start" or "Analyze" button on the software interface. The X-ray tube will activate, and the analysis will begin.

7. Wait for Results: The test typically takes 40 seconds. During this time, the X-ray tube emits X-rays, which interact with the sample, and the Customized Si-Pin detector collects the resulting fluorescent X-rays.

8. View Results: Once the test is complete, the results will be displayed on the screen. This will typically show the percentages of Au, Ag, Cu, Pt, Pd, and other detected elements from its broad element range (K~U), along with the calculated karatage for gold items.

9. Remove Sample: Open the chamber door and safely retrieve the tested item. XRF is non-destructive, so the item remains completely unharmed.

10. Continuous Operation: Thanks to its efficient heat dissipation system, there's no need to wait for cooling of system between tests, allowing you to proceed with the next sample immediately, which is ideal for busy retail settings.
