A modified quick, easy, cheap, effective, rugged, and safe (QuEChERS) method was established for simultaneous quantification of eight pharmaceutical molecules (2-hydroxyibuprofen, diclofenac, ibuprofen, propranolol, ofloxacin, oxazepam, sulfamethoxazole, carbamazepine) caffeine in environmental matrices. Analysis performed by ultra-high-performance liquid chromatography with tandem mass spectro...

In this study, pesticide residues in sauce manufactured from agricultural products were examined. A simultaneous multiresidue analysis for 260 pesticides samples was performed using liquid chromatography with tandem mass spectrometry (LC-MS/MS). The QuEChERS AOAC 2007.01 (quick, easy, cheap, effective, rugged, and safe) selected as the most suitable protocol routine determination of residues. l...

QuEChERS is a Quick-Easy-Cheap-Effective-Rugged-Safe extraction method that has been developed for the determination of pesticide residues in agricultural commodities. The European Standard is Method EN 15662:2008. While originally developed for plant matrices, the technique has since been adapted to be used in several applications and in many additional matrices. The rise in popularity of the ...
