Peptide fragmentation by corona discharge induced electrochemical ionization [PDF]
Journal of the American Society for Mass Spectrometry, 2010 Fundamental studies have greatly improved our understanding of electrospray, including the underlying electrochemical reactions. Generally regarded as disadvantageous, we have recently shown that corona discharge (CD) can be used as an effective method to create a radical cation species [M](+·), thus optimizing the electrochemical reactions that occur ...

Simulation and Study of DC Corona Discharge Characteristics of Bar-Plate Gap
Energies, 2022 In this paper, the corona discharge process of the bar-plate gap at −1 kV DC voltage is simulated using a two-dimensional axisymmetric plasma module. We analyze the variation of air negative corona discharge current, and the distribution morphology of ...

Study on Diphenylamine Oxidation by Ozone Using Atmospheric Pressure Chemical Ionization Mass Spectrometry. [PDF]
Rapid Commun Mass SpectromABSTRACT Rationale Diphenylamine (DPAH) derivatives, widely used as antioxidants, interact with oxygen molecules (or ozone) to form radicals at the amine group. Although the antioxidation mechanism involves radical processes, separating these radicals using chromatography is challenging. Methods Rapid oxidation of DPAH was achieved through ozonation in
