Comparison of the Internal Energy Distributions of Ions Produced by Different Electrospray Sources

[en] The internal energies of the emitted ions can be modulated in an electrospray source through different experimental conditions. However, the fragmentation pattern depends also on conditions that cannot be controlled by the operator. These differences make difficult the comparison of the electrospray mass spectra obtained with different mass spectrometers. A method for the calibration of the internal energies of ions produced by an electrospray source has been presented previously to study the influence of experimental conditions on the internal energies of the ions. In this work, new results were obtained with modified values of fragmentation energy taking into account the kinetic shift of thermometer ions.
