Influence of Na+- and K+- Concentration in Solvents on Mass Spectra of Peptides in LC/ESI–MS

LCGC Europe

In this article, the authors examine the concentration-dependent influence of Na+- and K+ ions on mass spectra of peptides, with human gastrin as a model peptide using LC/ESI–MS as the selected ionization technique.
