Analysis of Pesticide Residue in Spinach Using the AutoMate-Q40 QuEChERS Solution

In this application note, a LC/MS/MS was used to determine 14 pesticides from spinach using the AutoMate-Q40, an automated QuEChERS solution. Quantification was based on matrix-matched calibration curves with the use of internal standard to ensure method accuracy. QC samples were evaluated at levels of 20, 40, 100 ng/g to ensure precision and accuracy of the AutoMate-Q40.
