Determination of Pesticides in Coffee with QuEChERS Extraction and Silica Gel SPE Cleanup

This application note details an optimized method for the extraction and cleanup of pesticide residues from coffee using a QuEChERS extraction procedure followed by a silica gel SPE cleanup. Twenty representative pesticides, most of which are commonly used pesticides on coffee farms, were evaluated in this study. GC-MS was used for pesticide detection and quantification.
