Our VRAY Electronic Gold Testers operate on X-ray Fluorescence (XRF) principles, emitting X-rays to excite sample atoms, which then emit unique secondary X-rays. A high-resolution detector measures their energy and intensity for precise elemental identification and concentration. VRAY boasts superior accuracy, reaching 0.01% for 9999 gold (VR-S7), 0.05% (VR-M5), and 0.1% (VR-X3). Beyond machine wear, environment, operation, and item factors, accuracy is professionally impacted by:
Calibration: Quality and frequency using certified reference materials.
Matrix Effects: Absorption/enhancement by co-existing elements.
Spectral Overlaps: Interference from closely spaced X-ray peaks.
Detector Resolution: The detector's inherent ability (e.g., VRAY's SDD/Si-Pin) to separate signals.
Sample Geometry: Non-ideal sample thickness or surface irregularities affecting X-ray interaction.
These elements require sophisticated instrument design and software algorithms for optimal performance.
Power On: Initiate the machine's power, then launch the accompanying software.
Preheat Instrument: Allow the instrument to preheat for the recommended 10 minutes to ensure stable operation.
Calibrate: Place the designated calibration sample in the detection area for precise instrument calibration. This step is crucial for accuracy.
Place Sample: After successful calibration, carefully place your sample within the designated detection area.
Start Test: Ensure the machine cover (protective door) is tightly closed, then press the "start" button to begin the analysis.
Await Results: The preliminary analysis result typically appears in 3 seconds, with the complete, final analysis result available in 30 seconds.
Print/Save Report: Once the test is completed, select the "Print" icon. You can choose to print an A4 report or use a Bluetooth thermal printer. Alternatively, you may opt to save the report digitally without immediate printing.

A Thai gold refiner processing large volumes of scrap needed faster incoming material screening without sacrificing accuracy for final settlement (requiring 99.99% verification). We proposed a dual-solution: VR-X3 units for rapid initial sorting (detecting gross under-karat or heavily adulterated items) and the ultra-high precision VR-T6 for final certification batches. This tiered approach optimized workflow speed while guaranteeing the critical 0.01% resolution needed for certified 99.99% gold output.
A US pawn shop chain, facing inconsistencies across branches using older testers, sought a unified, foolproof solution for gold buying. Budget-conscious but demanding accuracy, they opted for the VR-M5 after comparing specs. The integrated computer eliminated external PCs, simplifying setup across 5+ locations. Staff training emphasized the intuitive interface and the analyzer's ability to detect common gold-plated fakes instantly, reducing risk and standardizing valuations chain-wide.
