Descrição

Aplicação

• Determination of pesticide residues in soybeans using QuEChERS followed by deep eutectic solvent-based DLLME preconcentration prior to gas chromatography-mass spectrometry analysis.: This study highlights a novel application of magnesium sulfate in pesticide residue analysis, employing it within the QuEChERS method to enhance preconcentration and detection capabilities in agricultural chemistry (Petrarca et al., 2024).
