Mechanistic investigation of ionization suppression in electrospray ionization
Journal of the American Society for Mass Spectrometry, 2000 We show results from experiments designed to determine the relative importance of gas phase processes and solution phase processes into ionization suppression observed in biological sample extracts. The data indicate that gas phase reactions leading to the loss of net charge on the analyte is not likely to be the most important process involved in ...
