Construction of a Digitally Operated Aerosol Laser Ablation Ion Trap Time-of-Flight Mass Spectrometer
Author: Nathan Michael Hoffman

ISBN:
Category :
Languages : en
Pages : 303
Book Description
Digital mass spectrometry offers the promise of unlimited mass range and enhanced functionality with existing instrument designs. The theoretical fundamentals of ion handling with digital waveforms have been well-established in the literature. Unfortunately, the lack of practical methods of implementing this theory is corroborated by the lack of publications describing analyses performed using digital mass spectrometry. The work contained herein describes methods of digital ion handling, the digital manipulation of ion stability, methods of controlling digital mass spectrometers, and digital waveform generation using microcontroller-based systems. The trapping of ions produced by laser ablation of aerosol particles is characterized as a function of various ion trap operating parameters. Three methods of low-voltage waveform generation providing a wide range of duty cycle resolution are discussed. The use of microcontrollers and analog-to-digital conversion for data acquisition is also covered in detail. Digital mass spectrometry is poised to expand the mass range of analysis by providing more capable instrumentation at lower cost than is achievable with current sinusoidal waveform technology. This work provides detailed descriptions of the practical methods by which this transition to digital mass spectrometry will be implemented down to the level of microcontroller firmware and hardware schematics.

Practical Aspects of Ion Trap Mass Spectrometry
Author: Raymond E. March
Publisher: CRC Press
ISBN: 9780849382536
Category : Science
Languages : en
Pages : 348
Book Description
By delivering concentrated information in three different volumes, the editors of the Practical Aspects of Ion Trap Mass Spectrometry mini-series present in-depth reviews on mainstream developments in each active and popular area. Contributing authors provide concise reports illustrating successful approaches to difficult analytical problems across the basic scientific disciplines. Ion Trap Instrumentation, the second volume in the series, conveys an appreciation of the ion trap as a versatile instrument which is used successfully in research and in applications, often in tandem with other instruments or components, such as external ion sources and lasers. The book begins with a discussion of high resolution mass spectrometry and mass measurement accuracy. It then demonstrates that trajectories of high kinetic energy ions can be controlled so that such ions are confined. It provides applications of lasers to the study of trapped ions the laser photodissociation of gaseous ions confined within the ion trap. The book concludes with physics applications of the ion trap, in particular, the Penning trap and the Paul trap.
