The extraordinary story of the three‐dimensional radiofrequency quadrupole ion trap,
accompanied by a seemingly unintelligible theoretical treatment, is told in some detail …

A new method of ion trap operation is disclosed in which the trap functions in a mass
selective instability mode. Relatively high pressures of a light gas are used to damp the ionic …

The use of an Ion-trap mass spectrometer to generate daughter spectra of selected parent
Ions Is shown. Ions are created within the trap by electron impact, undeslred Ions are ejected …

Beginning with the pseudopotential well approximation for Ion motion In the quadrupole Ion
trap, analytical expressions are derived for the Ion resonance ejection line shape …

A personal account of the quadrupole ion trap researches carried out in my laboratory and in
collaboration with other laboratories. This account commences with the announcement, in …

Methods which can be used to obtain mass spectra and tandem mass spectra by means of
quadrupole ion traps are reviewed and illustrated. High-order (MS n) experiments are …

Preliminary findings are presented of a simulation study of resonance excitation of gaseous
ions stored within a quadrupole ion trap. The ion trap was operated in the common mode …

The use of a radio-frequency ion trap having cylindrical geometry is considered. The
theoretical aspects of such a device are given in detail; some experimental studies and a …

Reflecting the substantial increase in popularity of quadrupole ion traps and Fourier
transform ion cyclotron resonance (FT-ICR) mass spectrometers, Practical Aspects of …

A program is described that simulates ion motion in a quadrupole ion trap. Based on the
Taylor series method, a numerical solution to the Mathieu differential equation is obtained …
