PCA of fused data of all 97 samples. Only PC 3 and 5 are shown here as they distinguish samples from positive and negative donors on the score plot. The loading plot shows some of the elements in all three sub datasets (LIBS 1, LIBS 2, ICP-MS), that distinguish the two clusters. Note Ba, Zn, P, Pb, Sr, Mg are correlated, and are anti-correlated to 385–384, 386, 358 and 330 nm.
