A Rapid Solution for Screening and Quantitating Targeted and Non-Targeted Pesticides in Water using the Exactive Orbitrap LC/MS

Instrument Type: LCMS

We describe a very simple, easy-to-reproduce screening and quantitation method to identify pesticides in surface water, ground water, and drinking water. All samples were analyzed by using online solid phase extraction (SPE) coupled to a Thermo Scientific Exactive high performance benchtop mass spectrometer. The acquired HRAM data was processed by using ExactFinder software for qualitative and quantitative data processing. Targeted pesticides were identified, and a number of non-targeted pesticides were confirmed by elemental composition. All samples underwent quantitative analysis.
