Portable Spectroscopy and Spectrometry, Volume 1
Description
Portable Spectroscopy and Spectrometry: Volume One is both a timely overview of the miniature technologies used in spectrometry, and an authoritative guide to the specific instruments employed in a wide range of disciplines. This much-needed resource is the first comprehensive work to describe the enabling technologies of portable spectrometry, explain how various handheld and portable instruments work, discuss their potential limitations, and provide clear guidance on optimizing their utility and accuracy in the field. In-depth chapters--written by a team of international authors from a wide range of disciplinary backgrounds--have been carefully reviewed both by the editors and by third-party experts to ensure their quality and completeness.
Volume One begins with general discussion of portable spectrometer engineering before moving through the electromagnetic spectrum to cover x-ray fluorescence (XRF), UV-visible, near-infrared, mid-infrared, and Raman spectroscopies. Subsequent chapters examine microplasmas, laser induced breakdown spectroscopy (LIBS), nuclear magnetic resonance (NMR) spectroscopy, and a variety of portable mass spectrometry instrument types. Featuring detailed chapters on DNA instrumentation and biological analyzers--topics of intense interest in light of the global coronavirus pandemic--this timely volume:
* Provides comprehensive coverage of the principles and instruments central to portable spectroscopy
* Includes contributions by experienced professionals working in instrument companies, universities, research institutes, the military, and hazardous material teams
* Discusses special topics such as smartphone spectroscopy, optical filter technology, stand-off detection, and MEMS/MOEMS technology
* Covers elemental spectroscopy, optical molecular spectroscopy, mass spectrometry, and molecular and imaging technologies
Portable Spectroscopy and Spectrometry: Volume One is an indispensable resource for developers of portable instruments, civilian and government purchasers and operators, and teachers and students of portable spectroscopy. When combined with Volume Two, which focuses on the multitude of applications of portable instrumentation, Portable Spectroscopy and Spectrometry provides the most thorough coverage of the field currently available.
