Multiresidue method was selected for the detection
of different pesticide residues in different samples.
A Thermofinnigan (LCQ Advantage Max, USA)
LC-MS system (LC Finnigan Surveyer) equipped
with a binary solvent pump and an auto sampler
was used. The system consisted of standard atmospheric
pressure ionization (API) source configured
as atmospheric chemical ionization (APCI). The
analytical column was ODS.3
