Classification: A61B,H01J

Abstract:
A mass-analyzing apparatus for a living body fluid, comprising:a microdialysis probe for collecting said living body fluid from a living body,a first flow passage through which an analyte solution including the living body fluid collected by the microdialysis probe flows,a second flow passage having a branched portion connected with an end portion of said first flow passage, said branched portion mixing the analyte solution with an organic solvent,a third flow passage through which the analyte solution mixed in said second flow passage flows,a fourth flow passage for causing a gas to flow around said third flowing passage,an ion source for spraying and ionizing the analyte solution from said third flow passage by a high speed gas from said fourth flow passage so as to provide ionized ions, andan analyzing unit for mass-analyzing the ionized ions in real time.
