Quadrupole mass filter operation under the influence of magnetic field (original) (raw)

“…In their original work much emphasis was placed on the fact that the QMS separates ions without the use of magnetic fields. Recent investigations have shown that applying a magnetic field to the body of the QMS electrode assembly can enhance device performance (Maher et al, 2013;Syed, Maher, and Taylor, 2013). At that time they filed patents in several countries for the QMS (Paul and Steinwedel, 1956) and the quadrupole ion trap (QIT), which utilizes a three-dimensional field to trap ions.…”

“…The results presented in this article are of interest beyond the solenoid-electron beam configuration studied. Our calculations demonstrate the feasibility of using such an approach for modelling charged particle optics in general [15][16][17][18][19].…”

“…Furthermore, this method may have implications for studying the influence of near-field EM interactions with biological bodies. Because the Weber force formulation describes moving charges and these do not necessarily have to be electrons in a copper wire, the theory might well be extended to charged particles in motion [47][48][49][50][51] or ionic species in biomedical systems [52][53][54], in particular providing insights into the effects of EM induction on specific biological processes.…”
