ABSTRACT:
An electrospray mass spectrometric method for analyzing an aqueous solution containing inorganic ion species first enhances the signals for small inorganic ions in electrospray mass spectrometric analysis of aqueous solutions by substantially diluting a sample of the aqueous solution with an organic solvent. The method also removes solvent molecules and other ligands from the small inorganic ions formed in electrospray ionization before mass analysis is complete, by appropriate application of electric fields to accelerate the ions so they will have energetic collisions with neutral gas molecules.
