Multi-Method for Pesticides by Single Quadrupole MS

Keywords multi-residue method pesticides fruits vegetables SPE cleanup single quadrupole MS. [Pg.546]

The effective monitoring of pesticide residues and its degradation products require fast and comprehensive multi-methods. The referenced method fulfils the requirement for monitoring a wide scope of pesticide compounds and degradation products in fruit and vegetable samples. [Pg.546]

The described internal standard method is suitable for the quantification of more than 200 components, using a single-quadrupole GC-MS. The extraction process with acetonitrile is followed by a clean-up including a salting-out step and solid phase extraction. The compound detection is done by SIM using the retention time and selected ion abundance ratios as qualifiers for identification. Two runs are required to determine the complete set of pesticides given in Table 4.10 according to the required SIM acquisition windows described as FV-1 and FV-2. [Pg.546]

The quantitation using Aldrin as internal standard is based on blank matrix spikes to compensate for matrix effects. [Pg.546]

In addition, the pubhshed method also includes the parallel determination of carbamates by HPLC with fluorescence detection (Health and Welfare Canada, 2000 Pillion, Sauve and Selwyn, 2000). [Pg.546]
