    • In ESI-MS, a dilute analyte solution is pumped through a needle to which a high voltage is applied. A Taylor cone with an excess of negative or positive charge on its surface forms as a result of the electric field gradient between the ESI needle and the counterelectrode. Charged droplets, formed at the tip of the Taylor cone, move towards the entrance of the mass spectrometer to produce free, charged analyte molecules by mechanisms that involve dividing large droplets into smaller and smaller ones (coulomb fission mechanism) and a release of ions from the droplet surface (ion evaporation mechanism). For reviews on the mechanisms involved in ESI-MS, see: a) P. Kebarle, L. Tang, Anal. Chem. 1993, 65, 972A-986A;

    • In the case of ESI-MS studies of simple analyte solutions, a linear response to changes in the concentration is usually monitored. However, the presence of co-solvents and additional species, such as salts, cause rather large decreases in the observed signal intensity (C. L. Sherman, J. S. Brodbelt, Anal. Chem. 2003, 75, 1828-1836). We found that in a titration experiment the systematic signal intensity decrease is excellently fitted with a parabolic function within the non-suppressed area.
