Abstract
The potential of gas chromatography with atomic emission detection (GC -AED) for pesticide multiresidue analysis is explored. Retention data of 181 phytochemicals of diverse properties and considerations about t he identification reliability and sensitivity are provided, making a c omparison with data obtained by mass spectrometric (MS) detection. The GC-AED system is applied to the determination of 11 herbicides in lab oratory-spiked soils after extraction with ethyl acetate. Complementar y use of MS is required in order to resolve some peak pairs undiscerne d by AED.
