*2.4. Mycotoxin Analysis by LC-MS*/*MS*

The samples were analyzed using a micromass Quattro Premier XE triple quadrupole mass spectrometer coupled with a Waters Acquity UPLC system (Waters, Milford, MA, USA). Data processing was done using the MasslynxTM (4.1 version) and Quanlynx® (4.1 version) software (Micromass, Manchester, UK). The analytical column used was a Symmetry C18, 5 μm, 2.1 × 150 mm, with a guard column of the same material (3.5 μm, 10 mm × 2.1 mm) (Waters, Zellik, Belgium) kept at room temperature. The injection volume was 10 μL. Capillary voltage was set at 3.2 kV with a source block temperature and desolvation temperature of 120 and 400 ◦C, resp. Liquid chromatography conditions and MS parameters were followed as described by Monbaliu et al. [75].
