Author information: An optimized analytical method was developed for the simultaneous analysis of 90 pesticides, 16 polycyclic aromatic hydrocarbons, and 22 polychlorinated biphenyls.
The method was based on quick, easy, cheap, effective, rugged, and safe QuEChERS extraction using acetonitrile followed by a dispersive solid-phase extraction cleanup using primary-secondary amine and octadecyl C The extract obtained was concentrated by evaporation and then reconstituted with acetonitrile to prepare it for chromatographic analysis by liquid chromatography-triple-quadrupole tandem mass spectrometry and gas anal tandem mass spectrometry, which was preceded by a preconcentration step using solid-phase microextraction with appropriate fibers.
The honey of the two extraction steps ensured efficient erotic dildo gif cleanup.
The use of the two analytical instruments allowed the analysis of a large number of pollutants with honey high reliability rate. The correlation coefficient R 2 anal was higher than 0.
Finally, the method was tested for its efficiency on real samples by the analysis of three honey samples in which seven pesticides and nine polycyclic aromatic hydrocarbons were determined.
