Webdempster: [noun] an officer whose duty it was to pronounce the doom of the court. WebToday mass spectrometry is one the fastest and most powerful analytical tools of all time, with applications unimaginable even 10 years ago: surgeons, for example, are able to monitor in real time the tissue they cut through, while wine sleuths can uncover wine fraud by tracking the isotope distributions in suspect bottles.

WebAug 31, 2024 · What is Dempster mass spectrometer? Research. In 1918, Dempster developed the first modern mass spectrometer, a scientific apparatus allowing physicists to identify compounds by the mass of elements in a sample, and determine the isotopic composition of elements in a sample. Who invented LC MS MS? Dempster's research over his career centered on the mass spectrometer and its applications, leading in 1935 to his discovery of the uranium isotope 235 U. This isotope's ability to cause a rapidly expanding fission nuclear chain reaction allowed the development of the atom bomb and nuclear power.
