A statistical model for identifying proteins by tandem mass spectrometry.

Analytical Chemistry, 2003
A statistical model is presented for computing probabilities that proteins are present in a sample on the basis of peptides assigned to tandem mass (MS/MS) spectra acquired from a proteolytic digest of the sample.

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

J. Anal. At. Spectrom., 1992
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.

Electrospray ionization for mass spectrometry of large biomolecules.

Science, 1989
Electrospray ionization has recently emerged as a powerful technique for producing intact ions in vacuo from large and complex species in solution. To an extent greater than has previously been possible with the more familiar "soft" ionization methods ...

Developments in ion mobility spectrometry–mass spectrometry [PDF]

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 ...

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
