چکیده
|
A novel multiresidue analytical method based on disposable pipette extraction (dpx) to determine the trace level of 28 pesticides in wine samples using liquid chromatography–tandem mass spectrometry (lc–ms/ms) has been developed. the dpx method is used for both extraction and purification. after the optimization, targets were eluted with 1% hcl in acetonitrile and the eluent was placed into lc analysis. the developed method exhibited good linearity (r2 > 0.99) for all 28 pesticides. satisfactory recovery of 28 pesticides was observed ranging from 71 to 109%, with the intraday relative standard deviations (rsds) and inter-day rsds of 1–11% and 3–18%, respectively. limits of detection (lods) and limits of quantification (loqs) were found to range from 1.5 to 3 μg/l and 5 to 10 μg/l, respectively. dpx was more suitable as compared with quick, easy, cheap, effective, rugged, and safe (quechers) and solid-phase extraction (spe) methods. the dpx method was applied to 47 commercial wine samples collected from china, and pesticide residues (0.02–0.09 mg/l) were found. in general, the developed method was highly reliable, selective, and sensitive for analyzing 28 pesticide residues in wine samples and would be applicable to other beverages.
