## Abstract A new tandem time‐of‐flight mass spectrometer with an electrospray ionization ion source ‘ESI‐TOF/quadTOF’ was designed and constructed to achieve the desired aim of structural elucidation via high‐energy collision‐induced dissociation (CID), and the simultaneous detection of all fragme

The performance of an energy sensitive, niobium superconducting tunnel junction (STJ) detector is investigated by measuring the pulse height produced by impacting molecular and atomic ions at different kinetic energies. Ions are produced by laser desorption and matrix-assisted laser desorption in a
A matrix-assisted laser desorption/ionization-quadrupole ion trap/reÑectron time-of-Ñight (MALDI-QIT/reTOF) mass spectrometer design and its operation in both normal and tandem mass spectrometric modes are described. A parabolic reÑectron was found to be capable of providing mass resolution of 5000
A tandem quadrupole ion-storage trap, time-of-flight instrument using matrix-assisted laser desorptionl ionization has been constructed. Desorbed ions are lint trapped in an RF' field and collisionally relaxed prior to time-of-!light mass analysis. So far masses up to 90 kDa, a resolution of up to 7
Designs of a quadrupole ion trap (QIT) as a source for time‐of‐flight (TOF) mass spectrometry are evaluated for mass resolution, ion trapping, and laser activation of trapped ions. Comparisons are made with the standard hyperbolic electrode ion trap geometry for TOF mass analysis in both linear and
