RE: Google AI response to can XRF tell if gold is present4 Dec 2025 14:53
Yes, an XRF gun is highly accurate for gold assay, often providing results with an accuracy of \(0.01\%\) to \(0.5\%\). The technology is fast, non-destructive, and can be used for various items like jewelry, coins, and bars. However, accuracy depends on proper calibration, a flat and clean sample surface, and the quality of the device.
