Magnetic solid phase extraction followed by high-performance liquid chromatography for the determination of sulphonamides in milk samples.


A simple and effective method based on magnetic solid-phase extraction combined with high performance liquid chromatography was used for the determination of nine sulphonamides in milk samples. The extraction and cleanup via silica-based magnetic adsorbent dispersion in milk samples followed by the magnetic isolation and desorption of the analytes using… (More)
