New Metal Sieve Technique Detects Fungicide Pyrimethanil in Food Samples

AI Insight

This study presents a novel analytical method combining metal sieve technology with double-syringe sugaring-out liquid-liquid microextraction for detecting pyrimethanil, a common fungicide, using gas chromatography-mass spectrometry (GC-MS). The technique aims to improve extraction efficiency and sensitivity compared to conventional methods by using a sugar-induced phase separation system integrated with a metal sieve filter and dual-syringe apparatus. The method was developed to provide accurate quantification of pyrimethanil residues in various sample matrices.


This analytical approach could enable more reliable monitoring of pyrimethanil residues in food products and environmental samples, supporting food safety regulations and consumer protection. The miniaturized extraction technique uses less organic solvents than traditional methods, making it more environmentally friendly and cost-effective for routine pesticide analysis in laboratories.
