Journal ArticleDOI
Direct determination of glyphosate using hydrophilic interaction chromatography with coulometric detection at copper microelectrode.
Cláudia F. B. Coutinho,Lincoln F. M. Coutinho,Luiz Henrique Mazo,Suzana Lucy Nixdorf,Carlos Alberto Paulinetti da Camara,Fernando Mauro Lanças +5 more
TL;DR: The present method was successfully applied for the determination of glyphosate in fruit juices without any kind of extraction, clean-up, or preconcentration step, with recoveries of 92 and 90% for apple and grape juice, respectively.
Journal ArticleDOI
Rapid and direct determination of glyphosate and aminomethylphosphonic acid in water using anion-exchange chromatography with coulometric detection
Cláudia F. B. Coutinho,Lincoln F. M. Coutinho,Luiz Henrique Mazo,Suzana Lucy Nixdorf,Carlos Alberto Paulinetti da Camara +4 more
TL;DR: The method was successfully applied to the determination of glyphosate and AMPA in water samples without any kind of extraction, clean-up, or preconcentration step.
Journal ArticleDOI
Copper Microelectrode as Liquid Chromatography Detector for Herbicide Glyphosate
TL;DR: In this article, the copper microelectrode can be used as coulometric detector for glyphosate in HPLC, using the complexation reaction in buffer solution, and the present method was successfully applied to the determination of glyphosate in tomato juice with a recovery of 88%.
Journal ArticleDOI
Novel devices for solvent delivery and temperature programming designed for capillary liquid chromatography
Lincoln F. M. Coutinho,Carlos Eduardo Domingues Nazario,Alessandra Maffei Monteiro,Fernando Mauro Lanças +3 more
TL;DR: The experimental results show that the miniaturized system can generate reproducible and accurate temperature and flow rate and that the system was applied to the separation of statins and tetracylines and showed excellent performance.
Journal ArticleDOI
