TI  - Analysis of nicotinoid insecticides residues in honey by solid matrix partition 
      clean-up and liquid chromatography-electrospray mass spectrometry.
PG  - 175-8
AB  - An analytical method for the routine simultaneous determination of four 
      nicotinoid insecticides (acetamiprid, imidacloprid, thiacloprid and thiamethoxam) 
      in commercial multifloral honey was developed. Fortified honey samples, dissolved 
      in water, were cleaned up through Extrelut NT20 column and, finally, insecticides 
      were eluted with dichloromethane. The eluate was evaporated, the residue 
      redissolved in methanol and then analyzed by LC-ESI(+)-MS. Average recoveries of 
      the four analytes were in the range of 76% and 99% at both spiking levels 0.1 and 
      1.0 mg kg(-1). Relative standard deviations (RSDs) were less than 10% for all of 
      the recovery tests. The detection limits (LODs) of the method ranged from 0.01 to 
      0.1 mg kg(-1) for the different insecticides studied. The developed method is 
      linear over the range assayed, 0.5-5.0 microg mL(-1), with linear correlation 
      coefficients higher than 0.9993.
