Pesticide Analysis in Agricultural Products by GC-MS/MS Using STQ Method

Abstract

As a method to detect pesticide residues in agricultural products, we evaluated the pretreatment of agricultural product samples by the solid-phase extracton technique with QuEChERS (STQ) method followed by GC-MS/MS with large-volume injection using a stomach-type glass-lined injector. This method satisfied the target criteria of recovery (70–120%) and the standard deviation of repeatability (RSD<25%) in 238–282 pesticides found in six types of agricultural products.
