Abstract

A mass spectrometric analysis of surface material is performed by vaporizing the surface material with pulses of laser light and then collecting the vaporized material by dissolving it in a liquid. The liquid with the dissolved material is then fed to an ionization process, preferably an electrospray ionization process. The resulting ions are then analyzed with a mass spectrometer. The method is particularly suited for use with imaging mass spectrometry.
