Simultaneous and Sensitive Determination of Multiple Mycotoxins in Wines by UHPLC Triple Quadrupole Mass Spectrometry Authors
A method for simultaneous determination of eight mycotoxins in wines, including aflatoxins B1, B2, G1, and G2, patulin, deoxynivalenol, ochratoxin A, and zearalanone was developed. The samples were initially extracted using acetonitrile in the presence of sodium chloride and magnesium sulfate. The resultant extracts were then subjected to concentration by rotary evaporation and redissolution fo...
متن کاملIdentification of aflatoxins by quadrupole mass spectrometry/mass spectrometry.
MS/MS daughter experiments were recorded for aflatoxins B1, B2, G1, G2, M1, M2, and aflatoxicol, using 3 ionization modes. Daughters were recorded from the molecular ion (M+) using electron impact ionization (EI). Daughters from the protonated molecules (MH+) were recorded in the positive ion mode and the daughters from the molecular anion (M-) were recorded in the negative ion mode using chemi...
متن کاملA Method Using Gas Chromatography – Mass Spectrometry for the Detection of Mycotoxins from Trichothecene Groups A and B in Grains
Mycotoxins are toxic secondary metabolites produced by several fungi species growing on many agricultural commodities and processed foods (Bennett & Klich, 2003). The term secondary metabolite designates compounds that are not indispensable for the growth and metabolism of the fungi as such, and in contrast to primary metabolites, such as amino acids, fatty acids, saccharides, nucleic acids and...
متن کاملQuadrupole ion trap mass spectrometry.
A number of other features of ITMS systems that will enhance their ability to analyze biological macromolecules are worth mentioning. As has already been demonstrated for ESI/quadrupole, ESI/magnetic sector, and ESI/FTICR systems, the capability of inducing fragmentation of the ESI-generated multiply charged ions of biological macromolecules in the capillary/skimmer region of the ESI source and...
متن کاملRapid determination of organophosphorous pesticides in leeks by gas chromatography...triple quadrupole mass spectrometry
A rapid multi-residue method was developed for the determination of 20 organophosphorous pesticide residues in leeks by gas chromatography coupled to triple quadrupole mass spectrometry (GC–QqQMS/MS). The method was based on the modified QuEChERS sample preparation method. After microwave pre-treatment, leek samples were extracted with acetonitrile containing acetic acid 0.1% and cleaned by dis...
