	abstract = {Linear ion traps are finding new applications in many areas of mass spectrometry. In a linear ion trap, ions are confined radially by a two-dimensional (2D) radio frequency (RF) field, and axially by stopping potentials applied to end electrodes. This review focuses on linear ion trap instrumentation. Potentials and ion motion in linear multipole fields and methods of ion trapping, cooling, excitation, and isolation are described. This is followed by a description of various mass discrimination effects that have been reported with linear ion traps. Linear ion traps combined in various ways with three-dimensional (3D) traps, time-of-flight (TOF) mass analyzers, and Fourier transform ion cyclotron resonance mass spectrometers are then given. Linear ion traps can be used as stand alone mass analyzers, and their use for mass analysis by Fourier transforming image currents, by mass selective radial ejection, and by mass selective axial ejection are reviewed.

	abstract = {A new hybrid linear ion trap time-of-flight mass spectrometer has been constructed and the first results for tandem-in-time MS/MS in a 2-dimensional Paul trap are presented. The instrument consists of an electrospray ionization source and two radio frequency (RF) only quadrupoles operating at a pressure of 7 mTorr N-2 which are coupled orthogonally to a linear TOFMS. Ions are trapped in an RF-only quadrupole through the application of timed stopping potentials on the entrance and exit apertures. Through the coupling of an auxiliary waveform generator on one pair of the ion trap rods a small dipolar excitation voltage is superimposed on the quadrupolar electric field. This voltage is used for precursor isolation via broadband excitation and collision induced dissociation through mass selective resonant excitation. Instrumental performance and choice of operating parameters are demonstrated by recording fragment spectra for +3 ions of renin substrate and fl ions of reserpine. TOFMS mass resolution (m/Delta m)(FWHM) is as high as 740 at m/z = 609. Fragmentation efficiency is greater than 50\% and excitation mass resolution is 60-75. (C) 1998 John Wiley \& Sons, Ltd.},
