More Information
Summary:A method for generating gaseous molecular ions for analysis by a mass spectrometer or ion mobility spectrometer comprises accelerating a sample toward a solid surface, wherein accelerating said sample comprises driving said sample via a pressure gradient along a tubular opening through which said sample is introduced from an atmospheric pressure regime to a lower pressure regime of a spectrometer, and wherein said sample comprises an aerosol sample comprising one or more molecular particle clusters. The method comprises colliding said sample with said solid surface to disintegrate said one or more molecular particle clusters, thereby forming one or more gaseous molecular ions and neutral molecules, and collecting said gaseous molecular ions and directing said gaseous molecular ions to an analyzer unit.
