...To improve on this point, FW Aston invented a mass spectrometer with velocity focusing, and AJ Dempster invented a mass spectrometer with a 180-degree magnetic field with direction focusing, and they discovered isotopes and measured their abundance ratios. In 1835, Josef Heinrich Elizabeth Mattauch (1895- ) and Richard Franz Karl Herzog (1911- ) created a double-focusing mass spectrometer, which had a resolution of ≌100,000 and a mass measurement accuracy of 10 -6 to 10 -7 .
