Analysis of Organophosphorus Pesticides in Baby Foods Using a Triple-Quadrupole GC/MS/MS System
Contamination of food products with pesticides is a growing concern because of recognized adverse health effects, increasing world-wide usage of pesticides, and increasing imports of raw foodstuffs from foreign sources. The concern is particularly acute for baby foods because of the high vulnerability of babies to adverse health effects from synthetic chemicals, particularly pesticides.
Triple quadrupole GC/MS/MS has emerged as the technique of choice for analysis of trace-level contaminants in complex matrices. Operation of the triple quadrupole GC/MS/MS in the Multiple Reaction Monitoring (MRM) mode provides unmatched sensitivity and selectivity for detection and quantitation of targeted pesticides at low concentrations in the presence of interfering background. This application note presents instrument configuration, operating parameters, and analytical results for analysis of trace levels of 24 organophosphorus (OP) pesticides in four different baby foods using the Shimadzu GCMS-TQ8030 triple quadrupole GC/MS/MS.
