TL;DR: The proposed method showed to be simple, easy, and adequate for high-throughput analysis of a large number of samples per day at low cost.
Journal ArticleDOI
High-throughput method for macrolides and lincosamides antibiotics residues analysis in milk and muscle using a simple liquid-liquid extraction technique and liquid chromatography-electrospray-tandem mass spectrometry analysis (LC-MS/MS).
Louise Jank,Louise Jank,Magda Targa Martins,Juliana Bazzan Arsand,Tanara Magalhães Campos Motta,Rodrigo Barcellos Hoff,Fabiano Barreto,Tânia Mara Pizzolato +7 more
TL;DR: A fast and simple method for residue analysis of the antibiotics classes of macrolides and lincosamides was developed and validated for cattle, swine and chicken muscle and for bovine milk and is able to be applied in routine analysis.
Journal ArticleDOI

TL;DR: A screening method for analysis of 46 antibiotics residues, belonging to different classes, such as tetracyclines, sulfonamides, fluoroquinolones, β-lactams, cephalosporins, macrolides and other minority groups was developed and validated for application in bovine milk, swine, poultry, equine, fish and shrimp meat samples as mentioned in this paper.
Journal ArticleDOI
A simple, fast and cheap non-SPE screening method for antibacterial residue analysis in milk and liver using liquid chromatography–tandem mass spectrometry

TL;DR: An efficient technique for the analysis of multiclass antibacterial residues (fluoroquinolones, tetracyclines, sulfonamides and trimethoprim) was developed based on simple, environment-friendly extraction for bovine milk, cattle and poultry liver and proved that it can be an important tool in routine analysis, since it is very fast and reliable.
Journal ArticleDOI
Determination of quinolones and fluoroquinolones, tetracyclines and sulfonamides in bovine, swine and poultry liver using LC-MS/MS
Magda Targa Martins,Fabiano Barreto,Rodrigo Barcelos Hoff,Louise Jank,Juliana Bazzan Arsand,Tiago Correa Feijó,Elfrides Eva Scherman Schapoval +6 more
TL;DR: A fast and simple analytical method for the determination of quinolones and fluoroquinolones, tetracyclines and sulfonamides in bovine liver samples using LC-MS/MS and accuracy was between 86% and 110%.
