Rapid Detection of Four Aflatoxins in Cereals by Supercritical Extraction-Supercritical Chromatography-Tandem Mass Spectrometry A method for the determination of aflatoxin in cereals by supercritical extraction-supercritical chromatography-tandem mass spectrometry was established. Methods the samples were extracted with supercritical CO2- methanol (98: 2, V/V) as extractant. The supercritical CO2 and methanol were used as mobile phase gradient […]
