N2 - Flowing afterglow atmospheric pressure glow discharge tandem mass
spectrometry (APGD-MS/MS) is used for the analysis of trace amounts of
pesticides in fruit juices and oil fruit peel. The APGD source was
rebuilt after Andrade et al. (Andrade et al.,Anal. Chem. 2008; 80:
2646-2653; 2654-2663) and mounted onto a hybrid quadrupole
time-of-flight mass spectrometer. Apple, cranberry, grape and orange
juices as well as fruit peel and salad leafs were spiked with aqueous
solutions containing trace amounts of the pesticides alachlor, atrazine,
carbenclazim, carbofuran, dinoseb, isoproturon, metolachlor, nietolcarb,
propoxur and simazine. Best limits of determination (LODs) of pesticides
in the fruit juices were achieved for metoicarb (I mu g/L in apple
juice), carbofuran and dinoseb (2 mu g/L in apple juice); for the
analysis of apple skin best LODs were 10 Pg/cm(2) of atrazine,
nietolcarb and propoxur which corresponds to an estimated concentration
of 0.01 mu g/kg apple, taking into account
