Unlabelled: A simple method based on solid-liquid extraction with a low-temperature partition (SLE/LTP) and analysis by gas chromatography coupled to mass spectrometry (GC-MS) was optimized and validated for determining residues of the pesticides triadimenol, flutriafol, λ-cyhalothrin, difenoconazole, and azoxystrobin in oat flour. A factorial design was employed to optimize the technique and establish the best conditions for the simultaneous extraction of the analytes. Acetonitrile-sample extraction and its 4 h freezing made it possible to recover the pesticides and clean the extracts in a single step.
