A sensitive and selective analytical method for the determination of 44 pesticide residues in several foodstuffs using the Agilent G6410AA Triple Quadrupole Mass Spec- trometer (QQQ) was developed. This method use two dif- ferent sample preparation methods followed by LC/MS/MS (liquid chromatography/tandem mass spec- trometry). The limits of detection for all pesticides were less than 10 ng/mL in foodstuff. The sensitivity of QQQ easily met the maximum residue limits (MRLs) of all investigated pesticides in Japan Food Hygiene Law.
The document details a developed analytical method for the determination of 44 pesticide residues in various foodstuffs. The method utilizes the Agilent G6410AA Triple Quadrupole Mass Spectrometer (QQQ) coupled with liquid chromatography/tandem mass spectrometry (LC/MS/MS). Two different sample preparation methods were employed to ensure the limits of detection for all pesticides were less than 10 ng/mL, meeting the maximum residue limits (MRLs) set by the Japan Food Hygiene Law.
