ABSTRACT
The Development of an analytical method for the determination of 24 multiclass pesticides in mango at the ≤10 ng g-1 level. The method involves extraction of 10 g of homogenized mango samples (2 g of Sodium chloride- +8g of Magnesium sulfate) with 10 mL of Acetonitrile; Clean up by Dispersive solid phase extraction with a combination of primary secondary amine (PSA), graphitized carbon black (GCB) and anhydrous Magnesium sulfate and final estimation by LC-MS/MS with multiple reaction monitoring (MRM) mode. The mean recoveries were in the range 80-120%. The method quantifies over a linear dynamic range of 10-100 μg/kg. The methodology has been proven to be highly efficient and robust and thus the method is suitable for monitoring the Maximum Residue Limits (MRL) compliance of a wide range of pesticides combinations.
