This European Standard stipulates a method for the analysis of pesticide residues in foods of plant origin, such as fruits (including dried fruits), vegetables, cereals and many processed products thereof by using GC, GC-MS(\/MS), and\/or LC-MS(\/MS). The method has been collaboratively studied on a large number of commodity\/pesticide combinations. Precision data are summarized in FprCEN\/TR 17063. Guidelines for calibration are outlined in FprCEN\/TS 17061.<\/p>\n
