An ion trap system was first introduced commercially in 1983 by Finnigan MAT (San Jose, Calif.), originally as a GC detector.

These electrodes form a cavity in which it is possible to trap (store) and analyze the ions.
WebbA review in 2000 summarized the mass analyzers used in miniature instruments, showing examples of virtually all the common types, including quadrupole mass filters, quadrupole ion traps, magnetic sector fields, TOF, and FT ion cyclotron resonance instruments. (9) More recent work has seen the commercialization of a novel toroidal ion trap system.
WebbThe moisture level of the CID and/or damper gas had a great effect in beam-like mass analyzers such as triple quadrupole, but not in trap-like mass analyzers, probably because of the long residence time that allowed adduct formation even with very low concentrations of water inside the mass spectrometer. top flight flight streakWebbDisregarding everything except the mass spectrometer analyzer and having worked in a laboratory with quads, ion traps, and time of flight instruments, the ion trap gives the highest... picture of henry townsendhttp://www.massspecpro.com/technology/mass-analyzers/quadrupole-ion-trap-qit top flight flagpole partsWebbReflecting the substantial increase in popularity of quadrupole ion traps and Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometers, Practical Aspects of … top flight flag pole partsWebb3 aug. 2016 · First of all, quadrupole can be used in two forms.
