A Gold Tester Machine operates on the principle of XRF spectroscopy. It directs a focused beam of X-rays onto the sample's surface. When these primary X-rays strike the atoms within the metal, they cause the atoms to emit secondary, fluorescent X-rays. Each element present in the sample emits these secondary X-rays at unique energy levels. The machine's highly sensitive detector captures these emitted X-rays, and its sophisticated software then analyzes their energies and intensities. This allows the machine to precisely identify the elemental composition (e.g., gold, silver, copper, nickel, zinc, palladium, platinum) and accurately quantify their percentages, thereby determining the exact purity (karat) of the gold or the composition of other precious metal alloys. The entire process is non-destructive, leaving the valuable item unharmed.

A Gold Tester Machine is primarily an X-ray Fluorescence (XRF) spectrometer specifically calibrated for analyzing precious metals. It's a non-destructive analytical instrument that precisely determines the elemental composition and purity (karatage) of gold, silver, platinum, and other alloys.
The machine emits a controlled beam of primary X-rays onto the sample. This excites the atoms within the metal, causing them to emit secondary, "fluorescent" X-rays with unique energy signatures characteristic of each element. A highly sensitive detector then captures and measures the energy and intensity of these fluorescent X-rays. Sophisticated software analyzes this data to identify the elements present (qualitative analysis) and their exact concentrations (quantitative analysis), providing a rapid and accurate karat reading (e.g., 10K, 14K, 18K, 24K). VRAY's Gold Tester Machines harness this advanced XRF technology to deliver reliable results in mere seconds.

The test accuracy of a Gold Tester Machine, particularly XRF analyzers, refers to how closely its measurements reflect the true elemental composition and purity of a sample. For VRAY's professional machines, the accuracy for 9999 gold ranges from 0.01% (for the high-end VR-S7) to 0.05% (for the portable VR-M5), indicating high precision across our product line.
Several key factors can significantly influence the test accuracy of an XRF Gold Tester Machine:
SDD (Silicon Drift Detector): Found in high-end machines like VRAY's VR-S7, SDDs offer superior energy resolution, higher count rates, and better detection limits, leading to the highest possible accuracy (e.g., 0.01% for 9999 gold) and the ability to analyze a broader elemental range (K to U).
Si-Pin Detector: Used in models like VRAY's VR-T6 and VR-M5, Si-Pin detectors provide excellent performance and good accuracy (e.g., 0.03%-0.05%) at a more economical cost, making them suitable for most commercial applications.
A powerful and stable X-ray tube (like VRAY's 50W micro-focused tubes) ensures consistent excitation of the sample, leading to more reliable fluorescent X-ray emission and thus better accuracy and precision, especially for trace elements.
The collimator focuses the primary X-ray beam. A smaller collimator (e.g., VRAY VR-S7's ϕ1.5mm vs. VR-T6's ϕ2.5mm) provides a more precise spot analysis, reducing scatter from surrounding material and improving accuracy for small or irregularly shaped samples.
The machine's accuracy is fundamentally dependent on proper and regular calibration using certified reference materials (standards) with known compositions. Outdated, incorrect, or insufficient calibration will directly lead to inaccurate test results.
While XRF is non-destructive, proper sample presentation is crucial:
Surface Condition: Clean, flat, and uniform sample surfaces yield the most accurate results. Dirt, oxides, coatings, or unevenness can significantly absorb or scatter X-rays, affecting measurements.
Sample Homogeneity: If the sample's composition is not uniform throughout (e.g., plated items, internal inclusions, layering), results may vary depending on the specific test spot. XRF typically analyzes only the surface layer.
Sample Geometry: The size, shape, and thickness of the sample relative to the test window can influence the X-ray path and detection efficiency.
Longer test times generally allow the detector to collect more X-ray photons, improving counting statistics and thereby enhancing the precision and accuracy of the analysis, particularly for elements present in lower concentrations. VRAY's 30-second test time balances speed with high precision for typical gold analysis.
Fluctuations in ambient temperature or humidity can affect the stability and performance of sensitive electronic components within the instrument, potentially impacting accuracy. Operating within the recommended environmental ranges (e.g., 10℃～35℃ for VRAY desktop models) is important.
The presence and concentration of other elements in the sample (the "matrix") can influence the absorption and emission of X-rays from the target element. Professional XRF software (like that in VRAY's i5 Windows 11 PCs) includes sophisticated algorithms to compensate for these "matrix effects" for more accurate results.
The skill and adherence to proper operating procedures by the user significantly contribute to achieving optimal accuracy. Incorrect sample placement, poor calibration practices, or misinterpretation of warnings can lead to less accurate readings.
For a professional Gold Tester Machine, adherence to relevant industry standards and obtaining specific certifications are crucial indicators of quality, safety, and reliability. VRAY ensures its products meet stringent international requirements. Key certifications and standards to look for include:
CE Marking (Conformité Européenne): This certification indicates that the product complies with the essential health, safety, and environmental protection requirements of European Union directives. It's a mandatory mark for products sold within the European Economic Area.
RoHS (Restriction of Hazardous Substances Directive): This directive restricts the use of certain hazardous materials in electrical and electronic products. Compliance signifies that the machine is environmentally safer.
ISO Standards: While not a direct product certification, a manufacturer's adherence to ISO standards, such as ISO 9001 (Quality Management Systems), indicates a commitment to quality manufacturing processes and continuous improvement.
National/Regional Radiation Safety Regulations: Depending on the country or region of operation, XRF devices must comply with specific local radiation safety laws and regulations issued by atomic energy commissions or public health authorities. Reputable manufacturers design their devices to meet these requirements.
NIST Traceability (for Calibration Standards): While not a machine certification, the accuracy of the Gold Tester Machine relies heavily on its calibration. Ensure that the reference materials (standards) used for calibration are traceable to recognized national or international standards bodies like NIST (National Institute of Standards and Technology) in the USA.
Manufacturer's Internal Quality Control: A professional manufacturer like VRAY implements rigorous internal quality control and testing procedures throughout the design, production, and final calibration phases to ensure each machine performs to its advertised specifications.
