Quick online classification allows the installation of the equipment in the line of work. In this sense, the laser-induced breakdown spectroscopy (LIBS) technique offers all the possible advantages: speed, possibility of online analysis, nondestructive, and so on. For the present work, a 350 mJ laser and Mechelle spectrograph were used. Analysis of the data with principal component analysis (PCA) allows an automatic classification of the aromatic herbal products like tea and camomile in a nondestructive and fast way.
