AEROSOL MASS SPECTROMETER COMPRISING EVAPORATION-ELECTRON IONIZER AND LASER IONIZER

摘要

The present invention relates to an aerosol mass spectrometer comprising an evaporation-electron ionizer and a laser ionizer. The aerosol mass spectrometer comprises a source device, a pressure maintaining device and an ionizing device. The ionizing device includes an evaporator to evaporate solid or liquid aerosol particles, which reach the ionizing device, to gas; and an evaporation-electron ionizer which is mounted outside a concentrating unit and has an electron gun to ionize the gaseous aerosol particles. The aerosol mass spectrometer further comprises a laser ionizer which is mounted at the lower part of the ionizing device and includes a reflector to reflect laser beams to a light condensing lens and the light condensing lens to condense the laser beams to the center of the ionizing device to evaporate and ionize the solid or liquid aerosol particles, which reach the ionizing device, thereby detecting all chemical compositions of a molecular-level, heavy metal, mineral, fire-resistant components, etc. using a single device.;COPYRIGHT KIPO 2015
