Figures & data
Figure 1. Total ion chromatogram of a spiked maize sample after clean-up with MycoSep® #227 column and subsequent gradient RP-HPLC with atmospheric pressure chemical ionization triple quadrupole mass spectrometry (HPLC–APCI–MS/MS) in multiple reaction monitoring (MRM) mode. Concentration of nivalenol (NIV), DON, Fusarenon-X (FUS-X), 3 Acetyl-DON + 15-acetyl-DON (= ADONs), Diacetoxyscirpenol (DAS), HT-2 and T-2 were determined at concentrations of 100 µg/kg each. DOM-1 was used as internal standard.
Figure 2. RP-HPLC-chromatograms of 1 ml aliquots after solid phase extraction of a beer sample (Coors Original) spiked with 1 µg/ml ZON. SPE with 100 mg cartridges of (1) control polymer and (2) quercetin imprinted polymer. 10 ml of beer was applied directly onto the SPE cartridges. Elution was performed with methanol containing 15% acetic acid. The Mobile phase: acetonitrile/water (1:1, v/v) with 0.1% acetic acid at a flow rate of 0.8 ml/min.
