Multiresidue Pesticide Analysis Using QuEChERS Method in Vegetable Samples by Ultra-Performance Liquid Chromatography

Multiresidue Pesticide Analysis Using QuEChERS Method in Vegetable Samples by Ultra-Performance... AbstractA multi-residue Ultra Performance Liquid Chromatography (UPLC) method has been developed and validated for the determination and quantification of 30 pesticide residues in vegetable. Samples were prepared by QuEChERS (Quick, Easy, Cheap, Effective, Rugged, Safe) method using acetonitrile as a solvent. And an additional clean up step of PSA and GCB is used. The composition of mobile phase was optimized to get good peak resolution and sensitivity. The developed method showed an average spiked recoveries of more than 80.0% and 105.0%. The method was applied to determine the pesticide residues in cauliflower, cabbage, onion, potato, chilli, bendi, brinjal and tomato samples. Trace amounts of acephate and cabaryl were found in chilli and potato samples respectively. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Analytical Chemistry Letters Taylor & Francis
