Název v původním jazyce

Analysis of multiple mycotoxins under ambient conditions using direct analysis in real time (DART) ionization coupled to high resolution mass spectrometry

Popis výsledku v původním jazyce

Direct analysis in real time (DART) ionization coupled to an (ultra)high resolution mass spectrometer based on orbitrap technology (orbitrapMS) was used for rapid quantitative analysis of multiple mycotoxins isolated from wheat and maize by modified QuEChERS procedure. After initial evaluation of ionization efficiencies for major groups of mycotoxins achievable with DART technology, sample preparation procedure and instrument parameter settings were optimized to obtain sensitive and accurate determination of most intensively ionizing toxins (deoxynivalenol, nivalenol, zearalenon, actyldeoxynivalenol, deepoxy-deoxynivalenol, fusarenon-X, altenuene, alternariol, alternariolmethylether, diacetoxyscirpenol, sterigmatocystin). The lowest calibration levels(LCLs) estimated for the respective analytes ranged from 50 to 150?gkg-1. Quantitative analysis was performed either with the use of matrix-matched standards or by employing commercially available 13C-labeled internal standards (available
