Study of an actinomycin complex by mass spectrometry-mass spectrometry

Talanta, 1988
The characterization of components within actinomycin complexes may often be complicated by the lack of material and standards of known actinomycins. Mass spectrometry-mass spectrometry can be employed both as a separatory device and as a means of structural analysis.

FIELDABLE MASS SPECTROMETRY FOR FORENSIC SCIENCE, HOMELAND SECURITY, AND DEFENSE APPLICATIONS.

Mass spectrometry reviews (Print), 2020
Mass spectrometry is commonly used in forensic chemistry laboratories for sensitive, definitive analysis. There have been significant efforts to bring mass spectrometry analysis on-site through the development of ruggedized, fieldable instruments ...

Mass Spectrometry and Tandem Mass Spectrometry of Citrus Limonoids

Analytical 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 ...

Mass spectrometry and proteomics

Current Opinion in Chemical Biology, 2000
Proteomics is the systematic analysis of the proteins expressed by a cell or tissue, and mass spectrometry is its essential analytical tool. In the past two years, incremental advances in standard proteome technology have increased the speed of protein identification with higher levels of automation and sensitivity.

Regulatory mass spectrometry

Biological Mass Spectrometry, 1981
The history of regulatory mass spectrometry at the Food and Drug Administration began in the early 1960s and was initiated by J. N. Damico using a time-of-flight instrument with limited mass range, resolution and sensitivity. Early work involved confirmation of identity of compounds using direct probe introduction and full mass scans. From 1964 to 1969

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 ...
