Analytical Technique for Quantifying of Residual Acetamiprid and Imidacloprid in Wheat

Abstract

This chapter presents an analytical technique for residue monitoring of selected neonicotinoids in crops and presents a fast, easy, and space-saving technique of sample preparation followed by a 100% water mobile phase high-performance liquid chromatography (HPLC) coupled photo-diode array detector (PDA) for quantifying acetamiprid (ATP) and imidacloprid (ICP) in wheat. The analytes were extracted from the sample using a handheld ultrasonic homogenizer with water, and purified by MonoSpin® C18-CX, a centrifugal monolithic silica spin mini-column, and quantified within 20 min/sample. The accuracy, precision, and system suitability are well within the international method acceptance criteria. The procedure may be recommended an international harmonized analytical method for ATP and ICP residue monitoring in real wheat.
