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 ...
