mL of the sample was loaded into the column at a rate of approximately 1–2 drops s1. The column was washed with 5 mL of distilled water. DON was eluted from the column using 2 mL of methanol. DON was quantified by the injection of 10 lL of diluted eluate into the HPLC-MS-MS system, which consisted of a Varian 212-LC Chromatography Pump and a 310-MS TQ Mass Spectrometer. The analytical column was a reverse Varian Polaris C18-A (100 2.00 mm, 3 lm) while the mobile phase was a gradient mixture of methanol and water fed at a flow rate of 0.2 mL/min. The DON retention time was 4.1 min with a runtime of 13 min.
