The diverse and expanding role of mass spectrometry in

mass spectrometry The advent of mass spectrometry (MS) as an analytical technology dates back more than a century and was made possible by the groundbreaking work on cathode rays of the physicist J. J. Thomson (Thomson, 1897). Thomson not only discovered the electron but, together with F. W. Aston, also measured the masses of stable

the mass spectrometer how it works

the mass spectrometer how it works

A simple description of how a mass spectrometer works. Note: All mass spectrometers that you will come across if you are doing a course for 16 - 18 year olds work with positive ions. Even if a few atoms in a sample of chlorine, for example, captured an electron instead of losing one, the negative ions formed wouldn't get all the way through the ordinary mass spectrometer.

The Role of Naturally Occurring Stable Isotopes in Mass

Mass Separation by Magnetic Deflection. When particles of mass m (kg) and charge q (coulombs) are accelerated from rest through a potential difference V, the loss in potential energy (qV) results in a corresponding gain of velocity v and thus of translational energy (mv2/2), so that: mv2 ∕ 2 = qV.
