Application Note: Analysis of Pesticide Residues in JonaGold Apples Using QuEChERS Approach and Comprehensive Two-Dimensional Gas Chromatography Time-of-Flight Mass Spectrometry (GCxGC-TOFMS)
5 April 2011

This poster shows the successful use of comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry (GCxGC-TOFMS) for effective screening and quantitation of pesticides in apples. JonaGold apples from Southwest Michigan were analyzed for potential pesticide residues following preparation by a QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) extraction approach. A cryogen-free thermal modulator was utilized for these analyses.
