The authors demonstrate a novel machine learning analysis technique for Cu and Cr in Mulberries. Samples were dried, powdered, sieved and then pressed into pellets prior to analysis. A key outcome was that the analytical performance was significantly improved by not using the full spectra, but by a subset of the data. |
