Using XRF Analysis for Geological Samples

2019-9-11  XRF is perfect for analyzing geological samples. Because XRF is known among geologists for being straightforward and quick, the importance of proper sample preparation is regularly overlooked. 6,7 Often, rock and mineral samples have varied particle sizes, rough surfaces, and non-homogenous compositions, which all decrease the accuracy of XRF results.
