Book excerpt: A novel ion mobility-mass spectrometer was designed and built in order to achieve high transmission and high resolution for observing desolvated ion conformations of chemical and biological molecules in the gas phase. The instrument incorporates a home-built electrospray ionization (ESI) source and rf ion funnel(IF) as an ion transfer interface, modular periodic-focusing ion guide (PFIG) as a drift tube (DT) for arrival time measurement, and orthogonally accelerated linear time-of-flight mass spectrometer to maximize analytical figures-of-merit of the instrument including sensitivity and separation of gas-phase ions. The rationales for implementation of each device aforementioned are discussed as enhanced ion focusing to reduce data acquisition time of the instrument, high mobility resolution (R > 56) to separate ions having a small collision cross section (CCS) difference at low-to-intermediate field strength (10 V cm−1 torr−1~19 V cm−1 torr−1), and observation of multiple conformers from isobaric ions at various operation conditions. Gate and transfer ion optic design needed to avoid detrimental gas dynamic effect is presented during hybridization of PFIG into ESI mass spectrometer. The details of instrumentation and electrode/voltage schematics are also discussed along with SIMION calculation results. The characteristic drift motions of ions inside the PFIG require a normalization procedure to compare CCS values from the instrument with the results using conventional uniform field DT ion mobility-mass spectrometry (IM-MS). Through experimental measurements and ion trajectory calculations from well known model peptides and proteins having multiple charge states, a correlation factor a which links the results from the two different types of instrumentation was derived and successfully applied (within ±4% difference). Ion heating was also investigated using ubiquitin, insulin, and substance P. Using ESI PFIG-MS, a significant variation of the arrival time distribution at different heated capillary temperature, rf amplitude, and electric field strength was observed for ubiquitin (+7) and (+8) and substance P (+3), while a substantial change was not observed for insulin owing to structural rigidity of disulfide bond cross-linking between two chains. The results imply that ESI PFIG-MS provides a window to monitor conformational variation of gas-phase ions and measure energy barriers of peptide/protein folding processes, which can allow us to reveal pathways in structural energy landscape.

Available in PDF, EPUB and Kindle. Book excerpt: Over the last decade, scientific and engineering interests have been shifting from conventional ion mobility spectrometry (IMS) to field asymmetric waveform ion mobility spectrometry (FAIMS). Differential Ion Mobility Spectrometry: Nonlinear Ion Transport and Fundamentals of FAIMS explores this new analytical technology that separates and characterizes ions by the difference between their mobility in gases at high and low electric fields. It also covers the novel topics of higher-order differential IMS and IMS with alignment of dipole direction. The book relates the fundamentals of FAIMS and other nonlinear IMS methods to the physics of gas-phase ion transport. It begins with the basics of ion diffusion and mobility in gases, covering the main attributes of conventional IMS that are relevant to all IMS approaches. Building on this foundation, the author reviews diverse high-field transport phenomena that underlie differential IMS. He discusses the conceptual implementation and first-principles optimization of FAIMS as a filtering technique, emphasizing the dependence of FAIMS performance metrics on instrumental parameters and properties of ion species. He also explores ion reactions in FAIMS caused by field heating and the effects of inhomogeneous electric field in curved FAIMS gaps. Written by an accomplished scientist in the field, this state-of-the-art book supplies the foundation to understand the new technology of nonlinear IMS methods.

Available in PDF, EPUB and Kindle. Book excerpt: Comprehensive, up-to-date coverage of a revolutionary technique Electrospray ionization mass spectrometry (ESI-MS) has completely changed the way physicists, chemists, and biologists view the study of large molecules. The technique derives detailed information about molecular weights and structures from extremely small sample quantities. ESI-MS can create highly charged forms of very high molecular weight compounds, it is naturally compatible with many types of separation techniques, and it allows noncovalent interactions between molecules in solution to be preserved in the gas phase. But many researchers may not use the technique to its full potential because they are unfamiliar with the different perspectives of its underlying processes, the varied approaches to implementation, and the wide-ranging utility of the technique. In this book, Richard B. Cole and an assemblage of leading researchers present a single-volume compilation of different approaches to the understanding and exploitation of ESI-MS. This comprehensive guide: * Examines the physical and chemical aspects of the electrospray process and describes the events involved in ion formation as well as the electro-chemical phenomena that are central to charged droplet formation during the process * Explores the coupling of electrospray ionization to various mass spectrometers, including quadrupole, magnetic, time-of-flight, quadrupole ion trap, and Fourier transform ion cyclotron resonance instruments * Describes recent progress in interfacing ESI with solution-based separation techniques, including liquid chromatography and capillary electrophoresis * Charts the rapid development of ESI applications and categorizes them by compound type: peptides and proteins, nucleic acids and their constituents, carbohydrates and lipids, small molecules related to pharmacology and drug metabolism, and organometallics and inorganic compounds Electrospray Ionization Mass Spectrometry is the indispensable handbook and reference for anyone who wishes to understand, implement, or apply this technique, including researchers in chemistry, metallochemistry, biochemistry, biology, pharmacology, and physics.

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.

Allen and published by . This book was released on 2017 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation reports the development of new ion mobility mass spectrometry (IM-MS) instrumentation to analyze protein and protein complex ions. IM-MS is a gas-phase analytical technique that separate ions based on their collision cross section (a description of ion shape) and mass-to-charge ratio. Electrospray ionization of samples from buffered solutions at biologically relevant pH generates “native-like” protein ions, which retain noncovalent interactions and compact conformations. IM-MS analysis enables the determination of the shape and assembly of native-like ions, which can be used to infer information about the solution conformations of biomolecules. New IM devices were developed to improve the informational content obtained from IM-MS experiments. First, an RF-confining drift cell was developed and implemented in a commercial mass spectrometer. Experimental results and ion trajectories implemented using SIMION were used to describe the separation principles of ions in RF-confining drift cells. Those results show that RF-confining drift cells separate ions similarly to traditional IM devices and that applied RF potentials have minimal effects on the effective temperatures of gas-phase ions. The RF-confining drift cells was used to report collision cross sections for 349 ions, 155 of which are for ions that have not been characterized previously using IM. The effects of ionization conditions and analyte solutions on the charge states and collision cross sections of ions was also investigated. An additional IM device based on Structures for Lossless Ion Manipulations (SLIM) was developed. SLIM is an emerging IM technology that can be implemented as modular platforms to perform ion separations, filtering, and trapping. The first collision cross sections determined using SLIM are reported. IM analysis of native-like protein ions shows that those ions exhibit significant structural heterogeneity in the gas-phase. To evaluate the stability and dynamics of native-like protein ions, IM-IM-MS functionality was implemented into the SLIM device. Dynamic gas-phase conformations were observed for native-like protein ions, which has significant implications for the broader community’s interpretation of IM-MS results. The stability of structural subpopulations of native-like ions was investigated as a function of gas-phase ion lifetime at near-ambient temperatures. The conformations of subpopulations evolve continuously in the gas-phase, but even after 4 seconds, the subpopulations exhibit different distributions of collision cross sections. This suggests that native-like ions in IM-MS experiments can retain some memory of their initial gas-phase structures for up to seconds at near-ambient temperature.

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.
