Book Description
Mass spectrometry is a powerful tool in the field of analytical chemistry. Though there have been numerous advances in mass analyzer technology over the decades, there has been comparatively little advancement in mass spectrometer detector technology. The development of the scientific charged-coupled device over 30 years ago brought the advantages of simultaneous detection over single channel detection to optical spectroscopy, including higher signal-to-noise ratios for a fixed analysis time, shorter analysis time to obtain a given signal-to-noise ratio, and greater sample throughput. While the use of array detectors to achieve simultaneous detection is commonplace in optical spectroscopy, ion detectors for mass spectrometry have lagged behind. Over the last decade, a new type of ion detector, the capacitive transimpedance amplifier (CTIA) array detector, has been developed that has a number of properties that make it an excellent tool for simultaneous detection using dispersive mass spectrometers. The CTIA array detector has high sensitivity as well as high gain stability, allowing it to excel in applications that require high precision measurements of ion signals, such as isotope ratio mass spectrometry. Capacitive transimpedance amplifier array detectors have previously been used to demonstrate the power of simultaneous detection on Mattauch-Herzog double focusing mass spectrometers, but the non-linear mass dispersion of these instruments means that the resolution is not constant across the array. A different type of dispersive instrument, the linear cycloid, has a linear mass dispersion, making it a good candidate for an array detector. The first detailed characterization of gain, read noise and dark-current noise, as well as of operating behavior over a range of temperatures, of the DM0025, a 1696 pixel CTIA array detector was performed. In addition, the first-ever combination of a CTIA array detector with a linear cycloid mass spectrometer was developed. This combined instrument demonstrated simultaneous detection of multiple masses, as well as a linear mass range. The results from the detailed characterization of the detector were used in conjunction with measurements of the performance of the combined instrument to suggest improvements for the next generation of linear cycloid instruments with CTIA array detectors.

Book Description
The resurgence of time-of-flight mass spectrometry (TOF-MS) has had its origin in the simplicity of construction and application of such instruments together with the high transmission and the great increase in resolution that has been achieved. The instrument lends itself naturally to a coupling with pulsed laser sources, though this is not a prerequisite. It also affords a time resolution far beyond that traditionally achieved with mass spectrometric rapid scan techniques - a recent example being the real-time analysis of a multi-component mixture from an automobile exhaust. Furthermore, the mass range appears to be extremely large: mass up to 500 kDa and beyond what is being readily measured in the laboratory today. The present set of contributions attempts to give a survey of current applications from many of the active groups in the field. A variety of new applications are considered which are no doubt just the beginning of large new areas of application. By presenting this work in book form it is hoped that it will be of help to the many groups intending to initiate work in this rapidly expanding new area of mass spectrometry.

Book Description
Provides comprehensive coverage of laser-induced ionization processes for mass spectrometry analysis Drawing on the expertise of the leading academic and industrial research groups involved in the development of photoionization methods for mass spectrometry, this reference for analytical scientists covers both the theory and current applications of photo-induced ionization processes. It places widely used techniques such as MALDI side by side with more specialist approaches such as REMPI and RIMS, and discusses leading edge developments in ultrashort laser pulse desorption, to give readers a complete picture of the state of the technology. Photoionization and Photo-Induced Processes in Mass Spectrometry: Fundamentals and Applications starts with a complete overview of the fundamentals of the technique, covering the basics of the gas phase ionization as well as those of laser desorption and ablation, pulse photoionization, and single particle ionization. Numerous application examples from different analytical fields are described that showcase the power and the wide scope of photo ionization in mass spectrometry. -The first general reference book on photoionization techniques for mass spectrometry -Examines technologies and applications of gas phase resonance-enhanced multiphoton ionization mass spectrometry (REMPI-MS) and gas phase resonance ionization mass spectrometry (RIMS) -Provides complete coverage of popular techniques like MALDI -Discusses the current and potential applications of each technology, focusing on process and environmental analysis Photoionization and Photo-Induced Processes in Mass Spectrometry: Fundamentals and Applications is an excellent book for spectroscopists, analytical chemists, photochemists, physical chemists, and laser specialists.
