Rapid quantitative thin layer chromatographic screening procedure for sulfathiazole residues in honey.
A procedure is presented for the quantitative determination of sulfathiazole residues in honey. Induced fluorescence of sulfathiazole is measured by fluorescent scanning densitometry; sulfaquinoxaline is added as an internal standard for quantitation. Recovery is greater than 98% and results are linear over the range 0.05-0.60 mg/kg. The detection limit, CL (k = 3), is 0.02. The procedure allows a single analyst to process 50-60 samples/day.
