Available in PDF, EPUB and Kindle. Book excerpt: A method is presented for using a mass spectrometer leak detector analytically for large systems. The method consists of calibrating the mass spectrometer, measuring the response time of the system being checked for leaks, and then utilizing these results in the system tests. The method has been used to measure leaks in two large (360 and 600 liters) heat exchangers of complex internal geometry. The response times of these vessels were 18 and 24 min, respectively, and the minimum detectable leak was about 4.6 x 10−10 std-cc/sec for each vessel.

Available in PDF, EPUB and Kindle. Book excerpt: Advances in Mass Spectrometry documents the proceedings of a Joint Conference on Mass Spectrometry held at the University of London, Great Britain on September 24-26, 1958. This compilation reviews the instruments, techniques, applications, and major developments in mass spectrometry over the past years. The topics discussed include the performance and image error correction of the new stigmatic focusing mass spectrograph; correction of second order aberrations in inhomogeneous magnetic sector fields; and high sensitivity solid source mass spectrometry. The isotope dilution analysis; digitization of mass spectra; ionization potentials of alkyl and halogenated alkyl free radicals; and negative ion formation and electric breakdown in some halogenated gases are also elaborated. This book likewise covers the mass spectrometer as a geological instrument and absorption and desorption of gases in the ionized state on metal and glass surfaces. This publication is a useful reference to students and researchers conducting work on mass spectrometry.

Download or read book Quadrupole Mass Spectrometry and Its Applications written by Peter H. Dawson and published by Elsevier. This book was released on 2013-10-22 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quadrupole Mass Spectrometry and Its Applications provides a comprehensive discussion of quadrupoles and their applications. It proceeds from a general explanation of the action of radiofrequency quadrupole fields to the description of their utilization in mass analyzers—such as the quadrupole mass filter, the monopole, the three-dimensional quadrupole ion trap, and various time-of-flight spectrometers—and finally to the characteristic applications of quadrupoles. A multi-author format has been adopted to provide broader-than-usual viewpoint in the book. The book begins by explaining the principles of operation of quadrupole devices. These include ion trajectories and computer simulations of performance; analytical theory; numerical methods of calculation of performance, including the recently developed application of phase-space dynamics; and fringing fields and other field imperfections. Subsequent chapters provide design and performance evaluations of the mass filter, the monopole, ion traps, and time-of-flight instruments; and describe areas of application where quadrupole devices have made the greatest impact because of their particular advantages and disadvantages.
