This application note provides a method for comprehensive detection of pesticides in vegetable juice matrices using GC/MS and LC/MS methods. Methods have been developed on Agilent GC/MS and LC/MS instrument platforms that reliably detect and quantitate 39 pesticides in a vegetable juice matrix. Most of the limits of quantitation (LOQ) values for GC/MS SIM ranged from 5 to 50 ng/mL, compared with 0.25 ng/mL to 10 ng/mL for GC/MS/MS, and 0.1 ng/mL to 10 ng/mL for LC/MS/MS. Both sensitivity and selectivity are improved using MS/MS and recovery of most spiked pesticides ranged from 70 to 120%.
