Screening and Quantitation of Pesticides in Jonagold Apples

Introduction

Screening and quantitation of pesticide residues in fruits and vegetables is of utmost importance for public health and safety concerns. These commodities can contain hundreds to thousands of analytes, making them extremely difficult for the screening and accurate quantitation of pesticide residues. Many current methodologies incorporate the use of complex, time consuming sample cleanup techniques to eliminate much of the matrix interference prior to analysis by GC-MS. As sample loads increase, analysts are forced to find ways to increase the speed of sample preparation and analysis while maintaining high quality of the analytical results.
