Features: This flagship desktop model is engineered for supreme accuracy. It boasts a high-sensitivity SDD detector for 0.01% accuracy for 9999 gold, a powerful 50W (50 kV, 1mA) micro-focused beryllium window X-ray tube, and a ϕ1.5mm collimator for precise spot analysis. Its spacious chamber (320 x 480 x 130mm) and manual XY sample platform, coupled with a 5-million-pixel high-resolution CMOS color camera offering 40x-160x magnification, enable detailed examination of intricate pieces.
Technical Solution: The VR-T7 utilizes the principle of X-ray Fluorescence with an SDD detector, which provides excellent energy resolution, allowing for superior separation of elemental peaks and thus, highly accurate quantification of gold and its alloying elements (K-U). Its robust hardware is complemented by advanced algorithms for precise data interpretation.
Features: Similar to the VR-T7 in its high-end analytical capability, the VR-S7 also features a high-sensitivity SDD detector for 0.01% accuracy for 9999 gold. Its distinguishing features include an 11.6" touchscreen and an inbuilt i5-1035G7 Windows 11 computer, providing a streamlined, integrated user experience within a compact desktop footprint (360 x 510 x 350mm).
Technical Solution: The "all-in-one" design integrates powerful computing directly into the XRF spectrometer, minimizing external hardware and simplifying setup. This solution leverages the SDD's performance for rapid and accurate elemental analysis of precious metals, offering a seamless workflow from analysis to data reporting.
Features: Designed for ultimate portability and on-site gold testing, the VR-H5 is a true handheld XRF gun. Weighing just 1.6Kg (with battery), it's equipped with a customized Si-Pin detector from USA for 0.03% accuracy for 9999 gold. It features a 4.3" industrial resistive touch screen, 32GB memory, and an intelligent battery system offering approximately 8 hours of continuous operation.
Technical Solution: This portable solution relies on energy dispersive XRF using a robust Si-Pin detector, optimized for rapid, accurate identification of gold purity and major alloying elements in field conditions. Its intelligent power management and compact excitation source (Up to 50KV/200μA, adjustable) ensure reliable performance on the go.
Features: Bridging the gap between handheld and desktop, the VR-M5 offers enhanced portability at 4.1Kg. It uses a customized Si-Pin detector from USA to achieve 0.05% accuracy for 9999 gold. It features a larger 5.7" retractable color touch screen and a built-in 5-million high-definition camera, providing improved visibility and documentation capabilities.
Technical Solution: The VR-M5's design balances robust analytical power with enhanced mobility. Its larger screen and integrated camera support more detailed sample viewing and data capture than smaller handheld units, while still being easily transportable for various gold testing scenarios.
Features: An accessible desktop option at $10,000-$11,000, the VR-X5 includes a customized Si-Pin detector offering 0.05% accuracy for 9999 gold. It comes with an inbuilt Intel i5 3320M computer, making it an integrated and cost-effective solution for general precious metal analysis.
Technical Solution: This model provides a solid XRF solution for users needing reliable desktop performance without the premium cost of SDD detectors, leveraging the Si-Pin's capabilities for accurate and efficient gold testing.
VRAY's XRF Analyzer for Gold Solutions are built on the principles of precision, non-destructive analysis, and user-friendliness, ensuring reliable results for every gold and precious metal testing requirement.
XRF Analyzers for Gold are essential tools across various industries, prized for their speed, accuracy, and non-destructive analysis. Here are six key applications:
Jewelry & Precious Metal Trading: Jewelers, pawn shops, and buyers use XRF analyzers (like VRAY's VR-T7 or VR-H5) to quickly and accurately determine karat purity (e.g., 10K-24K) and alloy composition (gold, silver, copper, palladium) of items, ensuring fair pricing and instant authentication.
Gold Refining & Recycling: Refineries use these XRF analyzers to assess incoming scrap gold and verify the purity of refined gold, aiding efficient sorting and process control to maximize value and meet specifications.
Mining & Geological Exploration: Portable XRF analyzers (e.g., VRAY VR-H5) are deployed on-site for rapid analysis of gold-bearing ore. This helps geologists quickly identify promising deposits and make real-time excavation decisions.
Quality Control in Manufacturing: Manufacturers of gold products (e.g., electronics, dental alloys) utilize XRF analyzers to ensure gold content and alloy composition meet strict quality standards for performance, durability, and cost control.
Numismatics & Collectibles: Authenticating gold coins, medals, and artifacts non-destructively, XRF technology allows collectors and dealers to confirm purity and composition without damaging valuable historical items.
Customs & Border Control: Customs officials employ XRF analyzers to swiftly screen gold shipments and articles, combating fraud and ensuring compliance with trade regulations by verifying authenticity and declared purity.
Operating an XRF analyzer for gold for precise purity testing is a straightforward process, thanks to modern instrument design. Here's a step-by-step guide:
Power Up: Turn on your XRF analyzer and allow it to complete its self-diagnostics.
Calibration Verification: Before each testing session, perform a quick calibration check using a certified gold standard (e.g., 24K gold standard). This confirms the instrument is reading accurately.
Radiation Safety: Always adhere strictly to the manufacturer's safety guidelines. Ensure the sample chamber door is closed and latched before initiating any test to prevent X-ray exposure. VRAY's XRF machines are designed with robust safety interlocks.
Cleanliness: Gently clean the gold item (jewelry, coin, bar) with a soft cloth to remove any dirt, oils, or residues that could interfere with the X-ray beam. Avoid abrasive materials that could scratch the item.
Positioning: Carefully place the sample directly into the XRF analyzer's sample chamber. For smaller or irregularly shaped items, use the designated sample holder or the manual XY platform (available on models like the VRAY VR-T7) to precisely position the area of interest under the X-ray beam.
Camera Alignment (if applicable): If your XRF analyzer has an integrated camera (like on VR-T7 or VR-M5), use the live camera feed on the screen to fine-tune the sample's position, ensuring the beam targets the desired spot, especially important for intricate jewelry.
Select Program: On the XRF tester's touchscreen or software interface, select the appropriate testing program. This is typically a "Gold Mode," "Precious Metals Mode," or "Jewelry Analysis" option.
Enter Sample ID (Optional): If your workflow requires, input a sample ID or description for record-keeping.
Start Test: Close the sample chamber securely. Press the "Start," "Analyze," or "Measure" button. The XRF equipment will emit X-rays, interact with the sample, and collect the fluorescent X-ray data. Analysis time is typically very fast, often around 30 seconds for VRAY models.
Review Data: Once the test is complete, the results will be displayed on the screen. This typically includes the elemental composition (e.g., Au%, Ag%, Cu%, etc.) and the calculated gold purity in karats (K) or fineness (parts per thousand).
Data Logging: Most XRF analyzers will automatically save the test results. You can usually review past measurements from the instrument's memory.
Reporting and Exporting: For documentation or further analysis, export the data to a USB drive (e.g., VRAY VR-H5, VR-M5) or directly to a connected computer. Many systems allow for customizable reports to be generated and printed.
By following these steps, you can efficiently and accurately perform gold purity testing using your XRF analyzer, ensuring reliable results for valuation and quality control.
