157-Drug Simultaneous Multi-Residue Testing Method

This technical report outlines the implementation of a 157-drug simultaneous multi-residue testing method for the management of veterinary drug residues in livestock and fishery products. The method specifies quantitative limits for various residues, including an exceptionally low limit of 0.0001 mg/kg for certain substances. It describes the application of an intelligent reflex function to enhance analytical productivity and accuracy, resulting in a 25% reduction in analysis time and significant improvements in interquartile deviation for high-concentration samples. The report details the calibration curve preparation, instrument analysis conditions, and the evaluation of productivity and accuracy improvements achieved through the intelligent reflex feature. It also presents data on the instrumental limit of detection for the analysis and the effectiveness of the method in reducing carryover and improving concentration accuracy. The findings indicate a marked enhancement in analytical efficiency and reliability when using the intelligent reflex function in conjunction with the multi-residue testing method.
