Abstract
A mass analyzer for the analysis of mass spectra of ions derived from organic molecules includes an electrospray ion source having means to transport the molecules of interest in a solvent of pure water free of organic solvents. The electrospray ion source sprays the water solution, under an imposed voltage, through a metal syringe needle having a sharp etched point and into a conductive capillary tube having a sharpened entrance orifice.
