YC/T 570-2018 in English

This standard provides a method for determining the residue of imidacloprid pesticide in tobacco and tobacco products. The method utilizes liquid chromatography-tandem mass spectrometry, which is a widely used analytical technique for detecting and quantifying trace levels of chemical substances. The procedure outlines the sample preparation, chromatographic conditions, and mass spectrometric analysis to ensure accurate and reliable results. It also specifies the equipment, reagents, and calibration procedures necessary for the analysis. The standard aims to establish a uniform approach for the detection of imidacloprid in tobacco products, facilitating quality control and regulatory compliance.
