SWIFTSIN: A High-Resolution Ion Isolation Waveform for the Miniaturized Linear ion Trap Mass Spectrometer by Coarse to Fine Excitation [PDF]
To figure out the reason for the drawback of the SWIFT waveform and realize the high-resolution ion isolation on the miniaturized linear ion trap mass spectrometer, we studied the efficiency that ions can be excited under different excitation durations ...

Electronic spectroscopy of cold ions in a radio-frequency trap [PDF]
The low density of ions in mass spectrometers generally precludes direct absorption measurements. The spectrum of ions can nonetheless be obtained by using resonance two-color photofragmentation or multiphoton photofragmentation techniques.

Electronic spectroscopy of cold cations in a 22-pole trap by indirect methods [PDF]
The confining capabilities of a 22-pole ion trap have been employed to mea- sure electronic spectra of cations of astrophysical relevance. The ion trap sits on the head of a closed cycle cryostat, enabling collisional cooling of the confined ions with

Ion-Trap-Performance Enhancement Utilizing Pulsed Buffer-Gas Introduction
A novel means of improving the resolution and total ion signal inside a digitally driven 3D quadrupole ion trap has been studied. Conventional ion-trapping methods occur by injecting helium gas continuously into the trap to kinetically cool ions and ...
