XRF Guns for Gold are highly versatile handheld XRF analyzers, offering rapid, non-destructive testing directly in the field. Their portability and speed make them invaluable across numerous applications:
Mobile Gold Buying & Pawn Shops: The primary use. Buyers (using VRAY's VR-H5) quickly and accurately assess karat value and alloy composition of gold jewelry, coins, and scrap on the spot. This ensures fair pricing and instant authentication without damage, boosting transaction trust.
Field Gold Prospecting & Mining: Geologists and prospectors use these portable XRF analyzers for rapid, on-site analysis of gold ore and soil. This helps identify promising deposits and make immediate decisions on excavation, saving significant time and resources.
Jewelry Manufacturing & Quality Control: Manufacturers employ XRF guns for swift quality checks of incoming gold alloys and verifying finished product purity, including gold plating thickness, directly on the production floor, maintaining brand integrity.
Recycling & Scrap Metal Sorting: Companies dealing with precious metal scrap use handheld XRF guns to rapidly sort and identify various gold alloys and other valuable elements from mixed materials. This efficient segregation maximizes value recovery.
Authenticating Historical Artifacts & Collectibles: Museums, auction houses, and collectors rely on XRF guns for non-destructive authentication of gold artifacts and coins. This allows precise elemental analysis to determine origin and purity without damaging irreplaceable items.
Customs & Border Security: Customs agents leverage the speed and portability of XRF guns to quickly screen gold shipments and articles at borders. This aids in verifying declared contents, combating smuggling, and ensuring trade compliance.
Charge Batteries: Ensure your XRF gun batteries are fully charged. VRAY's VR-H5 offers about 8 hours of use per battery.
Power On: Press and hold the power button to turn on the device. It will typically go through a brief self-calibration or warm-up sequence.
Clean the Sample: Before testing, gently clean the gold item (jewelry, coin, bar) using a soft cloth to remove any dirt, oils, or surface contaminants. A clean surface ensures the most accurate readings.
Safety First: Always follow the manufacturer's safety instructions. Ensure the XRF gun's analysis window is pointed away from yourself and others, and that the sample is properly placed before initiating the test.
Position the Sample: Place the gold item directly against the XRF gun's measurement window. For best results, ensure the sample is flat and covers the entire window area. For oddly shaped items, try to find a flat spot or use a sample holder if available.
Select Test Mode: Navigate the touchscreen (e.g., VR-H5's 4.3" industrial resistive touch screen) or controls to select the appropriate testing mode, usually "Gold Mode" or "Precious Metals."
Initiate Test: Once the sample is properly positioned and the mode is selected, pull the trigger or press the "Analyze" button. The XRF gun will emit X-rays. You might see an indicator light during the test (e.g., flashing from green to red).
Hold Steady: Keep the XRF gun steady and in full contact with the sample throughout the test duration, which is typically very fast (around 30 seconds for VRAY models).
Multiple Readings (Optional): For larger or potentially non-homogeneous samples (e.g., a gold chain, or if you suspect plating), take multiple readings at different spots and consider averaging the results for a more comprehensive analysis.
View Results: Once the test is complete, the results will instantly display on the screen. This will show the elemental composition (e.g., % of Gold, Silver, Copper) and often the calculated karatage (e.g., 14K, 18K, 24K).
Save Data: Most XRF guns have internal memory (like VR-H5's 32GB) to store results. You can save the data for record-keeping.
Export Data: If needed, transfer data via USB or Bluetooth (available on VRAY's VR-H5) to a computer for detailed reports or further analysis.
By following these simple steps, you can effectively use an XRF gun for gold to perform fast, accurate, and non-destructive gold purity testing.
