ASTON MASS SPECTROGRAPH PDF

Prof. F.W. Aston’s original Aston Mass-Spectrograph complete with magnet. The first mass spectograph was designed by Cambridge scientist F W Aston. Francis William Aston FRS (1 September – 20 November ) was an English chemist and physicist who won the Nobel Prize in Chemistry for his discovery, by means of his mass spectrograph, of isotopes. W. Wien’s first mass analysis to J.J. Thomson’s discovery of isotopes, F.W. Aston’s mass spectrometers, and the Mattauch–Herzog double focusing spectrometer.

Proceedings of the Royal Society A. A timely fellowship allowed Aston to work on isotopes independently of Thomson. He also planned to attend expeditions to South Africa in and Brazil in in later life. Aston studied the current through a gas-filled tube. The parabola method, however, just would not do. These instruments employing electromagnetic focusing allowed him to identify naturally occurring isotopes.

Thompson was thrilled by this, and hoped that he had discovered a new element. After the war, he returned to research at the Cavendish Laboratory in Cambridge and completed building his first mass spectrograph that he reported on in Asgon site uses cookies from Google and other third parties to deliver its services, to personalise adverts and to analyse traffic.
