Mass spectrometry of polyurethanes

Identification 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...

Mass Spectrometry of Glycans

The development of modern mass spectrometry (MS) equipment with high resolution and mass accuracy has led to its use in analyzing glycans for both profiling and structural studies. Unlike the HPLC method, a substantially larger amount (~10‐20 times) of glycan is normally required for a single MS spectrum. Matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry i...
