adaptability for the analysis of pesticide residues in beehive products seeking the development of an agroecosystem sustainability monitor.
forensic interest in blood by modifying the QuEChERS
Development and validation of a QuEChERS
based liquid chromatography tandem mass spectrometry method for the determination of multiple mycotoxins in spices.
Chromatographic analysis revealed small quantity of product in the lower stratum (Table 2), not consistent with the density of droplets collected in the water-sensitive cards (Table 1), because the samples were processed according to the modified QuEChErS
methodology (Lehotay et al., 2005), which is based on the extraction of 10 g of sample.
In this study, we developed a multiresidue test method based on the application of LC-MS/MS combined with modified QuEChERS
sample preparation methodology for rapid determination of nitroimidazoles and quinolones residues.

All the samples were processed through QuECHERS
kit and analyzed by using GC coupled with mass spectroscopy.
Samples were extracted using the Quick, Easy, Cheap, Effective, Rugged, Safe (QuEChERS
) multiresidue method for the analysis of pesticide residues in low fat matrix [20-22].
