Research Abstract

The purpose of this study was to construct a simple spectrometer for molecular ions in the gas phase, which is equipped with an electrospray ion source. We have placed a commercial electrospray ion source inside a fluorescence spectrometer, and tried to measure fluorescence spectra of tryptophan ions in water/methanol droplets emitted from the electrospray. The band position of the fluorescence spectra of tryptophan shifts from 347 to 366 nm with increasing the distance between the electrospray ion source to the measurement position from 0 to 12 nm. We conclude that this red-shift is due to the preferential evaporation of methanol over water during the travel of the droplets between the ion source to a grounded plate placed in front of the ion source. We also tried to achieve complete vaporization of solvent molecules from the ions by using a heated tube inside a vacuum chamber, and we obtained mass spectra of desolvated ions.
