Mass Spectrometry

2014
Over the last 100 years, mass spectrometry has become a critical aspect of geological science by providing ages from isotope–ratio measurements of natural radioactive decay. Mass spectrometry has also provided isotopic compositions of a myriad of solids, liquids, and gases that have been invaluable for understanding earth science processes, the rates ...

Developments in ion mobility spectrometry–mass spectrometry

Analytical and Bioanalytical Chemistry, 2001
Ion mobility spectrometry (IMS) has been used for over 30 years as a sensitive detector of organic compounds. The following is a brief review of IMS and its principles with an emphasis on its usage when coupled to mass spectrometry. Since its inception, IMS has been interfaced with quadrupole, time-of-flight, and Fourier-transform ion cyclotron ...

Infrared spectrometry

Applied Optics, 1982
A brief history of the early work on Fourier spectroscopy at the Johns Hopkins University is given as well as a general description of the techniques of Fourier and Hadamard transform spectroscopy. The techniques of tunable diode laser spectroscopy and the difference frequency technique for IR spectral studies are also briefly described including some ...

Atomic Spectrometry Update—Atomic Mass Spectrometry and X-Ray Fluorescence Spectrometry

J. Anal. At. Spectrom., 1995
The large number of papers covered in this year's review emphasizes the strong developments which continue in atomic mass and X-ray fluorescence spectrometries. Although much of the effort is aimed at improving existing technology and methodology, new and innovative instrumentation is also being developed in a number of fields.

Atomic Spectrometry Update—Inorganic Mass Spectrometry and X-ray Fluorescence Spectrometry

J. Anal. At. Spectrom., 1988
This year's Update includes an extended mass spectrometry section based on full abstracts and covering fully this extensive area of analysis. The newly introduced instrumentation for Glow discharge MS and the combined MS techniques are particularly notable this year. The ICP-MS section continues to grow in line with the increasing number of instruments
