The classification of rice samples was carried out based on elemental composition by a radar plot and multivariate data analysis, PCA and DA. [75] Tomatoes and triple concentration tomato paste DRC-ICP-MS The origin of tomato fruits and the areas of production as “Italy” and “non-Italy” of the triple concentrated pastes were evaluated by three supervised pattern recognition procedures, LDA, SIMCA and KNN [70] Sugar glass and coffee cream AsFlFFF–ICP-MS TEM for visualization of the particles For accurate characterization of TiO2NPs, fractions containing NPs were collected from the AsFlFFF system, concentrated, and Analyzed by TEM TiO2 was determined by ICP-MS after MAE digestion using On-line off-line and all the possible combinations [79] 207Pb, 208Pb (low resolution) (medium resolution) 51V, 52Cr, 54Fe, 56Fe, 57Fe, 60Ni, 66Zn (medium–high resolution) 75As, 82Se (high resolution) 26Mg, 27Al, 47Ti Al, As, Ba, Be, Ca, Cd, Ce, Cu, Dy, Fe, K, La, Lu, Mg, Mn, Na, Nd, Pb, Rb, Sm, Sr, Th, U, V, Zn Characterization of Nanoparticles TiO2NPs AES, atomic emission spectroscopy; AsB, arsenobetaine; AsC, arsenocholine; AsFlFFF, asymmetrical flow field-flow fractionation; DA, discriminat analysis; DRC, dynamic reaction cell; DMA, dimethylarsinic acid; HR, High resolution; iAs, inorganic arsenic; ICP, inductively coupled plasma; IC, ion chromatography; IEC, ion exchange chromatography; KNN, K-nearest neighbors; LDA, linear discriminant analysis; LOQs, limits of quantification; MA, methylarsonic acid; MAE, microwaveassisted extraction; MS, mass spectrometry; NPs, nanoparticles; OES, optical emission spectroscopy; PCA, principal component analysis; SIMCA, soft independent modeling of class analogy; TEM, transmission electron microscopy; TMAO, trimethylarsine oxide; TMAs, tetramethylarsonium ion.

Then, a sensitive and selective methodology has been developed for the rapid detection and quantification of the fraudulent addition of bovine milk to buffalo milk for the ‘Mozzarella di Bufala Campana’ production. The targeted quantitative analysis was performed by monitoring specific transitions of the phosphorylated beta-casein f33-48 peptide, identified as a novel speciesspecific proteotypic marker. [53] Botanicals Food supplements LC-ESI-LTQ-MS/MS PI-SRM and IDA-EPI For SRM transition >1500 cps, three EPIs were generated at three different collision energies, namely low (20 eV), medium (35 eV) and high energy (50 eV).

Principal component analysis (PCA) based only on the variation of the amount of the seven chemical markers was applied in order to find similarities between the hydroalcoholic extract and the food supplements [50]. A second PCA analysis was carried out considering the whole spectroscopic data deriving from LC-ESI-LTQ-MS analysis. High similarity between the two PCA was observed, showing the possibility to select one of these two approaches for future applications in the field of comparative analysis of food supplements and quality control procedures.
