A hybrid electrostatic analyzer/time-of-flight mass spectrometer was used to examine the matrix-assisted laser desorption/ionization (MALDI) ion kinetic energy distributions for Na Y , protonated 7-hydroxy-4methylcoumarin matrix ions and protonated bradykinin under a variety of source region acceler

## Abstract The ion kinetic energy of a helium microwave plasma is studied using an orthogonal acceleration timeβofβflight mass spectrometer. The ions produced in the plasma are extracted into the mass spectrometer in an βoffβconeβ mode (i.e. the helium plasma plume is off the sampler cone), and en
A time-of-flight mass spectrometer with an electrostatic mirror was used to probe the composition and structure of polyatomic secondary ions via their metastable dissociation following the impact of MeV energy primary ions. The experimental approach combines event-by-event bombardment and detection
Neutral IR-desorbed molecules of the amino acid tryptophan entrained in a supersonic beam were post-ionized by multiphoton ionization (MUPI) in the gas phase. Variations in the intensity of the ionization laser produced different degrees of fragmentation observed in the time-of-flight mass spectra o
