ABSTRACT

The resilience of environmental testing laboratories is constantly challenged by disruptions in the global supply chain, natural disasters, problems with instruments and facilities… In this work we will share a case study based on the improvements introduced in the analytical workflow for the analysis of herbicides included in Method EPA 8321 (2,4-D, 2,4-DB, Dalapon, Dicamba, Dichlorprop, Dinoseb, MCPA, MCPP, 2,4,5-T, 2,4,5-TP, Pentachlorophenol). We will also discuss the specific performance of the method for selected target compounds as an example of the suitability of the method for analyzing different environmental samples matrices (Soil and Water). The changes brought into routine operations enabled a greener method solely relying in methanol, acetonitrile and water as solvents, reduced the workflow length by 6x (including sample preparation and LC-MS/MS analysis), and minimized administrative burden related to procurement and management of chemicals and safety protocols.
