Abstract: A simple and sensitive method for the determination of ochratoxins A and B in nuts and grain samples was developed using an automated in-tube solid-phase microextraction (SPME) coupled with liquid chromatography-mass spectrometry (LC-MS). Ochratoxins were separated within 5 min by high-performance liquid chromatography using an Inertsil ODS-3 column with 5mM anmonium acetate/acetonitrile (65/35, v/v) as the mobile phase. Electrospray ionization conditions in the positive ion mode were optimized for mass spectr…
