The Encyclopedia of Mass Spectrometry Ten Volume Set by Anonim Book PDF Summary
Overview: The Encyclopedia of Mass Spectrometry The need for an encyclopedia of mass spectrometry (MS) becomes apparent when considering the subject’s evolution. By 1990, MS had evolved as a discipline and as a technique for solving problems in chemistry. Along with nuclear magnetic resonance and optical spectroscopy, it was a tool for compound identification. For complex mixtures as found in environmental chemistry, flavors, energy materials, and small-molecule metabolism, gas chromatography-mass spectrometry had become the premier analytical method. Despite these advances, MS played in 1990 only a small role in polar and large-molecule analysis. Field desorption, fast atom bombardment, and Cf-252 plasma desorption gently pushed it into peptide sequencing and molecular weight determination of larger polymers. Although these ionizations had limitations, when they were coupled with tandem mass spectrometers, the future became clearer. MS now awaited the development of new ionization methods that would extend its capabilities into many different research laboratories. The inventions of electrospray ionization (ESI) and matrix-assisted laser desorption ionization (MALDI) in the late 1980s opened the door for that greater role. Even the discipline of MS could expand by embracing the chemical-physical studies of proteins and oligodeoxynucleotides in the gas phase. The broad applicability of MS to a multitude of chemical, physical, and biological problems makes it now the central tool in chemical analysis. No longer a specialist’s tool, it has assumed broad applicability and availability. To permit a full and fruitful expansion in other disciplines, the Encyclopedia of Mass Spectrometry is designed to be a learning tool to newcomers who do not have the theoretical and practical background needed to take advantage of the possibilities of MS. Moreover, the field is now so broad that the specialist also needs a resource to allow exploration of its vast reaches. The encyclopedia meets that need and strives to be an entrance into the subject and to serve as its major reference work. Volume 1: Theory and Ion Chemistry Volume 1 begins with two theory chapters. The first discusses theoretical aspects of ion collisions, chemistry, and dynamics, and the second introduces ab initio calculations of ions. The latter has become a nearly indispensable tool in ion chemistry studies today. Instrumentation is essential in fundamental investigations. Chapter 3 introduces instrumentation, with an emphasis on unusual instrumentation, generally not commercially available. Ion traps, ion cyclotron resonance mass spectrometers, and time-of-flight instruments, which are important in both fundamental studies and in applications, are also covered. Chapter 4 discusses myriad means of performing spectroscopic experiments on ions. In the next chapter, various methods of measuring thermodynamic information about ions are introduced and evaluated. Collisional activation and dissociation processes, in various incarnations, are in Chapter 6. Mobility experiments are the focus of the next chapter, which covers fundamental aspects and applications of this rapidly growing technology. Various means and uses of changing charge states of ions is the topic of chapter 8. Chapters 9 and 10 introduce the ion chemistry of organic ions, positive and negative, respectively. The last three chapters (Chapter 11-13) are expositions of the ion chemistry of clusters and solvation phenomena, inorganic chemistry, and the rapidly expanding area of biochemistry.
