Download or read book Practical Aspects of Ion Trap Mass Spectrometry written by Raymond E. March and published by CRC Press. This book was released on 1995-09-18 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Ion Trap Mass Spectrometry presents an account of the development and theory of the quadrupole ion trap and its utilization as an ion storage device, a reactor for ion/molecular reactions, and a mass spectrometer. It also expands the appreciation of ion traps from that of a unique arrangement of electrodes of hyperbolic form (and having a pure quadrupole field) to a series of ion traps having fields with hexapole and octopole components and introduces the practical ion trapping device in which electrode spacing has been increased. The fundamentals of ion trap are covered in four chapters, beginning with the origin of the ion trap, its development and operating principles, and improvements in performance. The second part focuses on the environment within the ion trap -- the movement of ions within the trap -- and how this movement is modified by repeated collisions of the ions with buffer gas atoms of helium, and on the collisions of ions with molecules that lead to chemical change. The critical role of collisions in focusing the ion cloud for subsequent operations is emphasized. This important reference presents a coherent picture of the present status of research in the ion trapping field to facilitate the entree of potential ion trappers and provide a backdrop for ion trap research and development in the future.

Book excerpt: Development of a tandem mass spectrometer, consisting of a quadrupole ion trap (QIT) and a time-of-flight, is described for ion mass resolution and photophysics. Ions are generated externally by electrospray ionization and trapped in the quadrupole ion trap before extraction to the time-of-flight section for mass analysis. The non-parallel fields in the hyperbolic ion trap, which serves as the first acceleration region in the time-of-flight mass spectrometer, are shown to degrade spatial focusing and mass resolution. A novel short-pulse ion extraction method is shown to be useful in diagnosis of the trapped ion cloud size, energy and dispersal time. New ion trap geometries are evaluated theoretically for improvement in mass resolution as well as ion photophysics with similar ion trapping behavior compared with the existing hyperbolic ion trap. Parameters affecting mass resolutions in linear and reflectron time-of-flight modes are identified and possible improvements are discussed. An ion trap consisting of two endcaps and two ring flat electrodes is proposed and constructed on this basis. The newly optimized design is shown to yield the mass resolution of several thousand even at room temperature with moderate extraction field. Significant improvements in ion-laser interaction and photon collection are shown in the optimized design compared to the existing hyperbolic QIT. A molecular beam source is designed, fabricated and characterized for the application in ion-molecule collision experiments. Ionization methods, from solution to gas-phase, of small polycyclic aromatic hydrocarbons are developed and compared. A photo ionization source was designed and constructed to interface in the current mass spectrometer with fast switching capability with the current electrospray source.

Available in PDF, EPUB and Kindle. Book excerpt: Reflecting the substantial increase in popularity of quadrupole ion traps and Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometers, Practical Aspects of Trapped Ion Mass Spectrometry, Volume IV: Theory and Instrumentation explores the historical origins of the latest advances in this expanding field. It covers new methods for trapping ions, such as the OrbitrapTM, the digital ion trap (DIT), the rectilinear ion trap (RIT), and the toroidal ion trap; the development and application of the quadrupole ion trap (QIT) and the quadrupole linear ion trap (LIT); and the introduction of high-field asymmetric waveform ion mobility spectrometry (FAIMS). After a combined appreciation and historical survey of mass spectrometry and a discussion of how improved capabilities for microfabrication have led to interest in arrays of ion traps, the book examines the theory and practice of the Orbitrap mass analyzer, the rectangular waveform-driven DIT mass spectrometer, FAIMS, and ion traps with circular geometries. It next discusses ion accumulation for increasing sensitivity in FT-ICR spectrometry, a radio frequency-only-mode event for Penning traps in FT MS, and an FT operating mode applied to a 3D-QIT. The text then presents three behavioral aspects of quadrupole rod sets, before illustrating the development of the 3D-QIT in recent years. The final chapters explore photodissociation in ion traps and the chemical and photochemical studies of metal dication complexes in a 3D-QIT. In this volume that spans twenty-one chapters, a stellar panel of leading experts and up-and-coming researchers presents a cohesive, global, and up-to-date view of the practical aspects of using trapped ion devices. A companion to Volume V: Applications of Ion Trapping Devices, the book authoritatively covers the theory involved as well as the instrumentation currently used in this dynamic field.
