Development of a convenient HPLC-UV screening method for six antibiotic residues in chicken meat samples: model-driven gradient optimization and sorbent-free extraction with SALLME preconcentration.
The presence of antibiotic residues in poultry meat poses a growing risk of non-compliance with maximum residue limits under international food safety regulations. However, existing screening methods to detect antibiotic overuse rely mainly on LC-MS with dispersive solid-phase extraction (dSPE) clean-up using instrumen...
