In this study, a very sensitive method was validated to determine pesticides residues in fruit jams using micro flow liquid chromatography-tandem mass spectrometry (µLC-MS/MS). A slurry of the fruit jams and water was prepared to yield homogeneous samples. Because of the high sensitivity achieved with the µLC-MS/MS equipment and to minimize matrix effects, the QuEChERS extracts were diluted 30-...

This application note describes a method for the quantitative determination of 26 mycotoxins in sesame butter based on the work published by Liu et al. [1]. The sample was initially extracted and cleaned up using a modified QuEChERS protocol developed in the lab, and the resultant solution was subjected to separation and detection using an Agilent 1290 Infinity LC System coupled to an Agilent 6...

A high-resolution liquid chromatography-Orbitrap mass spectrometry (LC-Orbitrap MS) method was developed for simultaneous determination of 20 Fusarium toxins (nivalenol, fusarenon-X, deoxynivalenol, 3-acetyl deoxynivalenol, 15-acetyl deoxynivalenol, HT-2 toxin, T-2 toxin, neosolaniol, diacetoxyscirpenol, fumonisin B1, fumonisin B2, fumonisin B3, fumonisin A1, fumonisin A2, fumonisin A3, zearale...

The QuEChERS analytical method in combination with GC and LC-MS/MS was validated to quantify the insecticide residues immature kernel, mature cashew apple field soil. performance satisfactory LOQ, recovery RSD values. Residue persistence of betacyfluthrin imidacloprid on carried out after foliar spray formulation, 90 g -1 + 210 OD (Solomon) at recommended (2.5 ml 10 -1) double (5 doses. were be...
