Mass spectrometry combined with mass spectrometry

International Journal of Mass Spectrometry and Ion Physics, 1982
Abstract Tandem mass spectrometry (MS/MS) is a rapidly growing field of high promise for structure determination and quantitative analysis because of its sensitivity, specificity and speed. Rapid progress has been made in instrumentation, including the triple quadrupole and tandem double-focusing instruments, automated with on-line computers ...

Mass Spectrometry

2012
Mass spectrometry has evolved to become the biggest (in market share and total expenditure) analytical technology. It is also the analytical instrumentation sector with the biggest annual increase, thus signifying its importance and value. Mass spectrometry has become the method of choice because it offers unique characteristics not provided by other ...

Mass Spectrometry

2009
For twenty years or so now, mass spectrometry has been used to get exact measurements of the mass of biological molecules such as proteins, nucleic acids,oligosaccharides, and so on. Over the past ten years, this technology has followed the trend toward miniaturisation and the samples required can be much smaller.

Glycomics and Mass Spectrometry

Current Pharmaceutical Design, 2005
Proteomics is closely associated with the modifications of the gene product such as the post-translational events that yield functionally active gene products. Among these, glycosylation represents a critically important post-translational modification and is a target for proteomic research.

Mass Spectrometry and Tandem Mass Spectrometry of Citrus Limonoids [PDF]

open access: possibleAnalytical Chemistry, 2003
Methods for atmospheric pressure chemical ionization tandem mass spectrometry (APCI-MS/MS) of citrus limonoid aglycones and electrospray ionization tandem mass spectrometry (ESI-MS/MS) of limonoid glucosides are reported. The fragmentation patterns of four citrus limonoid aglycones (limonin, nomilin, obacunone, and deacetylnomilin) and six limonoid ...

Accelerator mass spectrometry

Analytical Chemistry, 1995
Accelerator mass spectroscopy (AMS) can be used for efficient detection of long-lived isotopes at part-per-quadrillion sensitivities with good precision. In this article we present an overview of AMS and its recent use in archaeology, geochemistry and biomolecular tracing.

Mass Spectrometry for the Masses

Journal of Chemical Education, 2004
Students in an introductory or nonmajors chemistry course have little to no background in scientific instrumentation. However, advanced instrumentation can be employed to further students' understanding of basic chemistry and scientific methods. In this article, we describe an experiment for an introductory chemistry course that incorporates the use of

Hybrid Instruments for Mass Spectrometry/Mass Spectrometry

Instrumentation Science & Technology, 1986
ABSTRACT In order to refine further the technique of mass spectrometry/mass spectrometry efforts are being made to combine the desirable features of sector based tandem instruments with those of triple quadrupole mass spectrometers. This has resulted in the construction of tandem mass spectrometers which incorporate both sector type analyzers and ...
