Differentiation of MGK-264 and ametoctradin using extracted ion chromatography (EIC) at high-mass resolution (42,000 FWHM): (a) spectra of MGK-264 and ametoctradin, showing ionization of the precursor ions ([M+H]+); (b) EIC showing the co-elution of these pesticides with low-mass accuracy (±500 ppm), resulting in no separation. The EICs of (c) MGK-264 and (d) ametoctradin at higher mass accuracies (±5 ppm), demonstrating clear separation between these analytes.
