Particle beam liquid chromatography/mass spectrometry (LC/MS) using negative ion chemical ionization was applied to the analysis of ivermectin residue in bovine milk and liver. Samples were prepared by liquid/liquid extraction followed by alumina B solid-phase extraction clean-up. On-line LC/MS of extracts was carried out on a C-18 bonded silica column… CONTINUE READING
