The utility model discloses a quick ionizationoun device, quick ionizationoun device include that sample container, mass spectrum advance kind passageway and heat energy generating device, sample container's open end is located the axis that the mass spectrum advances kind passageway, heat energy generating device establishes the bottom at sample container. The utility model discloses thereby the ionizationoun takes place for the eruption to utilize heat energy to make the sample produce fast, not only easily realizes, easy operation, can satisfy the ionizationoun requirement of the compound of different molecular weight size moreover, and low to need checking sample's selectivity, testable sample range of object is extensive, and the suitability is strong, and, treat that the analysis sample need not to carry out the pretreatment, simplified sampling operation, shortened the analysis time greatly, can realize the quick normal position analysis of mass spectrum.
