- Determination of Pesticide Residues in Honeybees using Modified . . .
In this article, we describe the evaluation and adaptation of the QuEChERS approach in combination with liquid chromatography–tandem quadrupole mass spectrometry (LC–MS MS) used to determine 19 pesticide residues in honeybee samples
- Efficiency of QuEChERS approach for determining 52 pesticide residues . . .
Multi-residue analysis of 80 environmental contaminants in honeys, honeybees and pollens by one extraction procedure followed by liquid and gas chromatography coupled with mass spectrometric detection
- Multiresidue Determination of Pesticide Residues in Honey by Modified . . .
In this study a new method for the determination of pesticides from different chemical groups in honey was developed and validated Honey samples were extracted by modified QuEChERS
- Determination of Pesticide Residues in Honeybees using Modified . . . - MDPI
In this article, we describe the evaluation and adaptation of the QuEChERS approach in combination with liquid chromatography–tandem quadrupole mass spectrometry (LC–MS MS) used to determine 19 pesticide residues in honeybee samples
- Ultrasound-assisted extraction based on QuEChERS of pesticide residues . . .
In this work, 260 pesticide residues, including insecticides, acaricides, fungicides, and herbicides, were extracted from honeybees using the QuEChERS methodology modified by applying an ultrasonic probe, which avoided the homogenization step and reduced the extraction time

- Comparison of Two Methods for the Determination of Selected Pesticides . . .
Developed and validated analytical methods for the determination of a wide spectrum of pesticide residues in honey and honeybee samples after the modification of QuEChERS extraction in combination with gas chromatography–tandem quadrupole mass spectrometry (GC-MS MS) and liquid chromatography–tandem quadrupole mass spectrometry (LC-MS MS) were d
- Determination of neonicotinoids and 199 other pesticide residues in . . .
Current work presents a modified QuEChERS method for the determination of 207 pesticide residues in honey by LC–MS MS and GC–MS MS Acetate buffered acetonitrile extraction with Z-Sep+ and PSA dispersive-SPE clean-up were used for sample preparation
- Determination of Pesticide Residues in Honeybees using Modified . . .
In this work, an analytical method employing liquid chromatography-tandem mass spectrometry (LC-MS MS) was optimized for the simultaneous screening of 19 pesticides which have not been
