quick polar pesticides method
QUICK POLAR PESTICIDES METHOD PROCEDURE Quick Polar Pesticides Method Il metodo QuPPe consente l’analisi dei residui di pesticidi molto polari, non adatti al metodo QuEChERS, sia negli alimenti di origine vegetale PO (frutta, ortaggi, cereali e prodotti trasformati), sia negli alimenti di origine animale AO (latte e uova). Il nuovo kit progettato per l’applicazione del metodo QuPPe-PO comprende: • Analoghi isotopicamente marcati come standards interni (ISTDs); • Miscele standard di pesticidi polari. Quick Method for the Analysis of numerous Highly Polar Pesticides in Foods of Plant Origin via LC-MS/MS involving Simultaneous Extraction with Methanol (QuPPe-Method) - Version 8.1 (March 2015, Document History, see page 58) Authors: M. Anastassiades; D. I. Kolberg; E. Eichhorn; A. Benkenstein; S. Lukačević; D. Mack; C. Wildgrube; I. Sigalov; D. Dörk; A. Barth Note: Changes from V7 to V8 are highlighted in yellow and changes from V8 to 8.1 are highlighted in turquoise Il nuovo kit progettato per l’applicazione del metodo QuPPe-AO comprende: • Tubi da centrifuga contenenti ODS (octadecilsilano) come adsorbente; • Analoghi isotopicamente marcati come standards interni (ISTDs); • Miscele standard di pesticidi polari.
