Behind the Science, S2 Ep 10: Kari Organtini on options for analyzing pesticides with GC-MS/MS

from Waters Corporation

When scientists in regulatory labs test fruits and vegetables, choosing the most appropriate mass spectrometry ionization mode to screen for hundreds of pesticides can be challenging. Some pesticides, like bifenthrin, fragment under electron impact ionization. Senior scientist Kari Organtini shows Jen Fournier an increasingly popular technology that uses GC-MS/MS at atmospheric pressure - or APGC - and is available as a simple source change for a triple quadrupole mass spectrometer so the MS can be used with either GC or LC. See the application note detailing the method: http://bit.ly/2ukVp1W
