Sažetak
The LC-MS/MS was used in the positive mode with ESI. The method was set for the detection of 55 pesticides in a single injection. The validation procedure for the method was carried out using blank sweet pepper samples spiked with a solution of 55 pesticides at four levels: 0.02, 0.05, 0.1 and 0.2 μg/ml with the addition of internal standard carbofuran–D3. The linearity of the method was investigated in the range from 5 to 250 g/kg. The obtained R2values were higher than 0.99.The recoveries were in the 80-110 % range and were characterized by precision lower than 20 %. The LODs were calculated using the Agilent MassHunter B.04.00 software, and the LOQs were experimentally set at 0.02 mg/kg. The data processing of the analyzed pepper samples, collected directly from domestic farmers, indicate that all pesticide detections were below the MRLs.
