On-line trapping of ions injected into a quadrupole ion trap

Journal of Physics D: Applied Physics, 1981
The use of a quadrupole trap to catch ions in flight was investigated numerically. The results show that storage is possible for injection into a trap operated in the radio-frequency and the combined modes, but not in the Penning mode.

Extraction of trapped ions from the Tokyo electron beam ion trap

Physica Scripta, 1997
A beam line for transporting highly charged ions extracted from the Tokyo Electron Beam Ion Trap is being constructed in order to study ion-surface interactions and to inject into secondary ion traps for atomic physics experiments. A basic idea for the design and a computer modeling for the extraction system are described.

Ion traps

2004
Abstract In a trap operating with a voltage of 10 = 500 V, singly-charged ions have a maximum ‘binding’ energy of order 500eV.3 This trap depth corresponds to the kinetic energy at a temperature of 6 x 106 K. This is more than enough to trap ions, even if the ions do receive a large recoil kick during the ionization process-to load an

Fundamental studies of ion injection and trapping of electrosprayed ions on a quadrupole ion trap

International Journal of Mass Spectrometry, 1999
Abstract The quadrupole ion trap is a highly versatile and sensitive analytical mass spectrometer. Because of the advantages offered by the ion trap, there has been intense interest in coupling it to ionization techniques such as electrospray which form ions externally to the ion trap.

The effect of ion trap temperature on the dissociation of peptide ions in a quadrupole ion trap

International Journal of Mass Spectrometry, 2011
Abstract Thermally-assisted collision-induced dissociation can substantially increase the amount of dissociation in quadrupole ion trap mass spectrometer experiments. The experiments discussed here were performed to assess the effect on dissociation pathways as the bath gas temperature is increased in thermally-assisted collision-induced dissociation

Hydrolysis of thioesters in an ion trap

Rapid Communications in Mass Spectrometry, 2008
Abstract The alkenyldiarylmethanes are a class of non‐nucleoside reverse transcriptase inhibitors that are currently being developed as potential antivirals for the treatment of HIV infection and AIDS. As part of our continuing investigations on the alkenyldiarylmethanes, a series of thioester analogues were ...

Ion Traps

1995
Abstract The author provides, in nine chapters, a compact and up-to-date coverage of the entire range of applications of the two most important ion traps: the Paul('radiofrequency') trap and the Penning('dc) trap. The book begins with full details of the ion confinement principles of both these traps; this is followed by a ...
