Abstract: According to some embodiments, systems and methods for rapid evaporation of liquid phase samples are provided. The method includes directing liquid samples to a thermal evaporation ionizing device, thermally evaporating the liquid samples to create gaseous molecular ions, and directing the gaseous molecular ions to an ion analyzer to analyze and provide information regarding the chemical composition of the liquid samples.

Abstract: The present invention provides for a system, method, and device for analyzing, localizing and/or identifying tissue types. The method includes analyzing, localizing and/or identifying one or more tissue samples, characterized in that the method comprises: (a) generating gaseous tissue particles from a site in the one or more tissue samples, (b) transporting the gaseous tissue particles from the site to an analyser, (c) using the analyser for generating tissue-related data based on the gaseous tissue particles, and (d) analyzing, localizing and/or identifying the one or more tissue samples based on the tissue-related data. The invention can either be used in close conjunction with a surgical procedure, when one or more surgical tools are an integrated part of ionization, or as a separate mass spectrometric probe for the analysis of one or more tissue parts.
