An information obtaining method for obtaining information about a mass of a component of an analyte using a time of flight mass spectrometer and obtaining information about a distribution state of the component based on the obtained information about the mass includes the step of: (1) adding a self-reactive substance to the analyte on a base to facilitate ionization of the component; (2) irradiating the analyte with a primary beam in the presence of the self-reactive substance, thereby ionizing the components and allowing resulting ions to fly; (3) obtaining information about mass of the flying ions using the time of flight mass spectrometer; and (4) obtaining information about the distribution state of the component on the base based on the information about the mass.
摘要:
A method is provided by which a reagent is provided to a living sample, including contacting a thin-film containing a porous body with a living sample containing cells or tissues, and discharging a solution containing at least one or more reagents to a non-contact side of the thin-film by ink-jet to provide the solution to the specific area of the living sample through pores on the thin-film, wherein the smaller diameter of the pores on the porous body relative to the diameter of cells in the living sample enables the reagent to be provided to each individual cell separately. According to this method, the reagent and the reaction product can be fixed while maintaining positioning information of the target substance in the living sample, as a pretreatment for analyzing with high positioning accuracy the target substance in each individual cell in the living sample.

摘要:
A sample is sliced obliquely with a blade provided with a metal thin film on the surface, and the slice of the sample adhering to the blade surface is subjected to mass spectrometry. As a result, the section of the sliced sample can be analyzed immediately by mass spectrometry with high sensitivity.
