Ion kinetic energy

WebThe impact of a secondary discharge cannot be overemphasized with respect to its effect on the kinetic energy of the ions being sampled. It is well documented that the energy spread of the ions entering the MS must be as low as possible to ensure they can all be focused efficiently and with full electrical integrity by the ion optics and the mass separation device. WebMass-analysed ion kinetic energy (MIKE) and collision-activated dissociation/MIKE spectra provide characteristic fragment ions which permit differentiation of the 6- and/or 8 …

Kinetic energy release distributions in mass spectrometry

Mass-analyzed ion kinetic-energy spectrometry (MIKES) is a mass spectrometry technique by which mass spectra are obtained from a sector instrument that incorporates at least one magnetic sector plus one electric sector in reverse geometry (the beam first enters the magnetic sector).

WebThe period of the alternating voltage course is set at T, so while the particle is inside D1, moving along its semicircular orbit in a time T/2, the polarity of the dees is reversed.When the particle reenters the gap, D1 is positive with respect to D2, and the particle is again accelerated across the gap, thereby gaining a kinetic energy qV.The particle then … WebElectron ionization was first described in 1918 by Canadian-American Physicist Arthur J. Dempster in the article of "A new method of positive ray analysis." It was the first modern mass spectrometer and used positive rays to determine the ratio of the mass to charge of various constituents. In this method, the ion source used an electron beam directed at a …
