Screening and Quantitation of Pesticides in Jonagold Apples by Comprehensive Two-Dimensional Gas Chromatography- Time-of-Flight Mass Spectrometry (GCxGC-TOFMS)

This application shows the utility of GCxGC-TOFMS when combined with a rapid QuEChERS extraction approach. Compounds such as sugars and fatty acids, which can be left behind even after sample clean up, often lead to chromatographic interferences in one-dimensional chromatography. In this example, the enhanced peak capacity of the GCxGC separation is critical to removing the interferences which can ultimately lead to quantitation bias.
