We realize fast transport of ions in a segmented microstructured Paul trap. The ion is shuttled over a distance of more than 10(4) times its ground state wave function size during only five motional cycles of the trap (280 μm in 3.6 μs). Starting from a ground-state-cooled ion, we find an optimized transport such that the energy increase is as low as 0.10±0.01 motional quanta. In addition, we d...

A combined electrodynamic ion funnel and ion trap coupled to an orthogonal acceleration (oa)-time-of-flight mass spectrometer was developed and characterized. The ion trap was incorporated through the use of added terminal electrodynamic ion funnel electrodes enabling control over the axial dc gradient in the trap section. The ion trap operates efficiently at a pressure of approximately 1 Torr,...

The construction and operation of a Penning ion trap is described in which the trapping field is provided by a cladded NdFeB permanent magnet. Studies with atomic ions show that the trap can provide stable ion confinement for extended periods ~*100 ms! making it suitable for use in a wide variety of applications. Use of the trap to measure the lifetime of excited SF6 * and C7F14 * ions produced...

A novel instrumental setup for measuring infrared photodissociation spectra of buffer gas cooled, mass-selected ions is described and tested. It combines a cryogenically cooled, linear radio frequency ion trap with a tandem mass spectrometer, optimally coupling continuous ion sources to pulsed laser experiments. The use of six independently adjustable DC potentials superimposed over the trappin...

A new approach was recently introduced to improve the structure elucidation power of tandem mass spectrometry simulating the MS(3) of ion trap mass spectrometry system overcoming the different drawbacks of the latter. The fact that collision induced dissociation in the triple quadrupole mass spectrometer system provides richer fragment ions compared to those achieved in the ion trap mass spectr...

a fast, accurate, sensitive, selective and reliable method using reversed-phase high performance liquid chromatography coupled to electrospray ionization ion trap mass spectrometry was developed and validated for the determination of finasteride in human plasma. after protein precipitation with perchloric acid, satisfactory separation was achieved on a zorbax eclipse® c8 analytical column using ...

55th ASMS Conference – Indianapolis 2007 www.chemistry.wustl.edu/~msf/ Overview Purposes •Evaluate the resolving power and sensitivity achievable with a new compensated trap for FTMS as a function of m/z and develop a protocol for tuning this trap. Methods •Sample empirically the cyclotron frequency surface at various cyclotron radii and z-mode amplitude distributions. •Compare the mass resolvi...
