A Person's Achievement
BACKGROUND OF THE INVENTION 1. Field of the Invention Mass in 1913, the Aston in the Cavendish Laboratory, with J. J. Thomson, together with the study of the isotope neon, he found that most elements are identified in several different mass but the same chemical properties as the atomic set composition after the end of World War I, he continued to be presented, in 1919 he invented that first Taiwan uses electromagnetic focusing composition after the end of World War I, he continued to be presented, in 1919 he invented that first Taiwan uses electromagnetic focusing .
mass spectrometry using mass spectrometry, he quickly found the 287 naturally occurring isotopes of at least 212 species of mass spectrometry using mass spectrometry, he quickly found the 287 naturally occurring isotopes of at least 212 species of . He won a1922 MS and discovery of isotopes in nonradioactive elements.

1900 onwards, he studied at the Birmingham School of wine fermentation, and by W. Butler wineries hire until 1903 returned to the University of Birmingham and worked as a research assistant of Poynting 1909, Aston became a lecturer at the University of Birmingham, 1909, Aston became a lecturer at the University of Birmingham, .
a year later, by J. J. Thomson's invitation in favor of the University of Cambridge Cavendish Laboratory after the beginning of the First World War, and was forced to interrupt his studies, during the period of enlistment with the Royal Air Force service after the beginning of the First World War, and was forced to interrupt his studies, during the period of enlistment with the Royal Air Force service .

Academic Contribution
In 1903, at the University of Aston in Birmingham; in the discharge vessel of the Crookes dark space, soon discovered the "Aston dark zone phenomenon" In 1903, at the University of Aston in Birmingham; in the discharge vessel of the Crookes dark space, soon discovered the "Aston dark zone phenomenon" . Aston joined the Cavendish Laboratory, Thomson has been research on cathode rays in substantial outcome, instead in Eugen Goldstein discovered anode rays Aston joined the Cavendish Laboratory, Thomson has been research on cathode rays in substantial outcome, instead in Eugen Goldstein discovered anode rays .
Thomson and William Wayne Aston used the method of the invention, the magnetic field by the anode ray deflection of particles occurs, and by an electric field having a different charge and mass of the ions separated by Thomson and William Wayne Aston used the method of the invention, the magnetic field by the anode ray deflection of particles occurs, and by an electric field having a different charge and mass of the ions separated by . these experiments the result, the first magnetic sector mass spectrometer of the birth of causing ions along a parabolic flight,its track record to the chassis, so as to determine its precise quality these experiments the result, the first magnetic sector mass spectrometer of the birth of causing ions along a parabolic flight,its track record to the chassis, so as to determine its precise quality .
in the Cavendish Laboratory at the beginning, Aston has been proved by experiments in the presence of two isotopes of neon in the Cavendish Laboratory at the beginning, Aston has been proved by experiments in the presence of two isotopes of neon . later due to World War I, his studies were interrupted in later due to World War I, his studies were interrupted in .
5, 1919, he returned to the laboratory, continue on the study of the isotope neon 5, 1919, he returned to the laboratory, continue on the study of the isotope neon . soon, he has successfully developed the first mass spectrometer, and is produced through successively higher, second and third soon, he has successfully developed the first mass spectrometer, and is produced through successively higher, second and third .
by means of these electromagnetic focusing performance of the mass spectrometer, he at least identify 212 naturally occurring isotopes by means of these electromagnetic focusing performance of the mass spectrometer, he at least identify 212 naturally occurring isotopes . in the abundance of isotope research, he describes the "integer", i.e., all elements except hydrogen,Its atomic mass is the mass of the hydrogen atom are integral multiples of the
and, by means of mass spectrometry analysis, he explained according to the actual value and the deviation of the rule because of the existence of isotopes and, by means of mass spectrometry analysis, he explained according to the actual value and the deviation of the rule because of the existence of isotopes . the Aston's life occurred in many papers, published in 1922 ("isotopes"), reprinted in 1933 when it was renamed as the - and Mass - spectra (" mass spectrometry with isotope " the Aston's life occurred in many papers, published in 1922 ("isotopes"), reprinted in 1933 when it was renamed as the - and Mass - spectra (" mass spectrometry with isotope ".
