Oxidation Artifacts in the Electrospray Mass Spectrometry of Aβ Peptide

Gradual corrosion of stainless steel electrospray emitters under conditions of normal use generates surface irregularities that can promote electrical discharge. The increased emission current affects the electrochemical reactions associated with the spray process. When sampling the peptide Aβ(1−40)...
