Potential of fourier transform mass spectrometry (orbitrap and ion cyclotron resonance) for speciation of the selenium metabolome in selenium-rich yeast

HIGHLIGHTS

• who: Joanna Szpunar from the France, Laboratory of Molecular Dietetics, IM Sechenov First State Medical University (Sechenov University) have published the Article: Potential of Fourier Transform Mass Spectrometry (Orbitrap and Ion Cyclotron Resonance) for Speciation of the Selenium Metabolome in Selenium-Rich Yeast, in the Journal: (JOURNAL)
• what: The main reason is a big excess of the concomitant matrix species with regard to the selenium analyte concentration and the consequent suppression of the Se-species ionization efficiency which requires the isolation and purification of the analytes.
