GC/MS and LC/MS are both useful techniques for the detection and quantification of pesticides in difficult matrixes such as fruit juices; however, each has their own advantages and limitations. Here we analyse 39 pesticides in fruit juice using a combination of GC/MS, GC/MS/MS, and LC/MS/MS and present results that highlight the need for different approaches for different compounds. In order to meet tight regulations in food safety testing, food testing laboratories should employ a variety of techniques to ensure pesticides may be detected at levels below established maximum residue levels (MRLs).
