Journal ArticleDOI
Detection and confirmation of milk adulteration with cheese whey using proteomic-like sample preparation and liquid chromatography-electrospray-tandem mass spectrometry analysis.
T.M. Campos Motta,T.M. Campos Motta,Rodrigo Barcellos Hoff,Fabiano Barreto,R.B.S. Andrade,D.M. Lorenzini,Leonardo Zanchetti Meneghini,Tânia Mara Pizzolato +7 more
TL;DR: A proteomic-like technique is developed using liquid chromatography coupled to mass spectrometry with electrospray ionization able to differentiate and subsequently quantify CMP and pseudo-CMP in milk samples in order to identify adulteration or contamination of these products.
Journal ArticleDOI
Structural Elucidation of Sulfaquinoxaline Metabolism Products and Their Occurrence in Biological Samples Using High-Resolution Orbitrap Mass Spectrometry
Rodrigo Barcellos Hoff,Leonardo Zanchetti Meneghini,Tânia Mara Pizzolato,Maria do Carmo Ruaro Peralba,M. Silvia Díaz-Cruz,Damià Barceló +5 more
TL;DR: Four previously unreported metabolism products of sulfaquinoxaline (SQX), a widely used veterinary medicine, were isolated and analyzed using liquid chromatography coupled to high-resolution Orbitrap mass spectrometry, and a fragmentation pathway was proposed.
Journal ArticleDOI
Multivariate Optimization for Extraction of Pyrethroids in Milk and Validation for GC-ECD and CG-MS/MS Analysis
Leonardo Zanchetti Meneghini,Gabriel Rübensam,Vinicius C. Bica,Amanda Ceccon,Fabiano Barreto,Marco Flôres Ferrão,Ana Maria Bergold +6 more
TL;DR: The method has been applied to routine analysis for determination of pyrethroid residues in bovine raw milk in the Brazilian National Residue Control Plan since 2013, in which a total of 50 samples were analyzed.
Journal ArticleDOI
Pharmaceuticals, pesticides and metals/metalloids in Lake Guaíba in Southern Brazil: Spatial and temporal evaluation and a chemometrics approach.
Maurício Perin,Alexsandro Dallegrave,Lucas Suchecki Barnet,Leonardo Zanchetti Meneghini,Adriano de Araújo Gomes,Tânia Mara Pizzolato +5 more
TL;DR: In this paper, data sets from different sources were combined using a data fusion approach to produce a spatial and temporal variation of contaminants presents in water from Lake Guaiba (29°55'-30°24' S; 51°01'-51°20' W).
Journal ArticleDOI
Chemometric evaluation of darifenacin hydrobromide using a stability-indicating reversed-phase lc method
Leonardo Zanchetti Meneghini,C. A. Junqueira,A. S. Andrade,Fernanda Rodrigues Salazar,Cristiane Franco Codevilla,Pedro Eduardo Fröehlich,Ana Maria Bergold +6 more
TL;DR: A set of chemometric tools including in silico simulation and design of experiments (DOE) were used to develop and validate an RP-LC/UV method for darifenacin hydrobromide.
