Extraction and preconcentration technique for triazole pesticides from cow milk using dispersive liquid-liquid microextraction followed by GC-FID and GC-MS determinations.
TL;DR: A simple and rapid dispersive liquid-liquid microextraction (DLLME) technique coupled with gas Chromatography-flame ionization detection (GC-FID) and gas chromatography-mass spectrometry ( GC-MS) was developed for the extraction, preconcentration, and analysis of triazole pesticides in cow milk samples.
