AOAC 2017.09 Pesticide Residues in Citrus Fruits Laboratory Testing Service: A Comprehensive Guide

The AOAC 2017.09 method for the determination of pesticide residues in citrus fruits is a widely accepted and recognized standard for laboratory testing services. This section provides an overview of the relevant standards, legal and regulatory framework, international and national standards, and standard development organizations.

ISO/IEC 17025:2005

The International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) have established ISO/IEC 17025:2005, which is a widely accepted standard for laboratory testing services. This standard outlines the requirements for laboratories to demonstrate their competence in carrying out tests and calibrations.

AOAC 2017.09 Method

The AOAC 2017.09 method is based on the QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) approach, which involves a series of steps for sample preparation, extraction, cleanup, and analysis. The method is designed to be sensitive, specific, and robust, making it suitable for determining pesticide residues in citrus fruits.
