Electrospray Mass Spectrometry and Tandem Mass Spectrometry of Bimetallic Oxovanadium Complexes

Electrospray and tandem mass spectrometry in biochemistry.

Over the last 20 years, biological MS has changed out of all recognition. This is primarily due to the development in the 1980s of 'soft ionization' methods that permit the ionization and vaporization of large, polar, and thermally labile biomolecules. These developments in ionization mode have driven the design and manufacture of smaller and cheaper mass analysers, making the mass spectrometer...

Electrospray tandem mass spectrometry of 2H-chromenes.

Several 2H-chromenes derived from carbazoles were analyzed by electrospray tandem mass spectrometry. The 2H-chromenes constitute an important class of compounds that exhibit photochromic activity. The fragmentation pathways of the protonated molecular species [M+H]+ were studied, and main fragmentation pathways of these compounds were identified. Fragmentation pathways of [M+D]+ ions were also ...

Electrospray mass spectrometry of metal carbonyl complexes †

Methods are described for characterising neutral metal carbonyl complexes using electrospray mass spectrometry, by converting them into ions with suitable reagents. Ionisation techniques included addition of OMe generating [M 1 OMe] species, addition of Ag or Na ions giving the appropriate positive ion, abstraction of acidic hydrogen forming [M 2 H] ions, or (in rare cases) oxidation giving rad...

Electrospray tandem mass spectrometry of intact beta-chain hemoglobin variants.

In this report, we present data to illustrate how human hemoglobin (Hb) variants can be identified by electrospray tandem mass spectrometry (MS/MS) of the intact Hb chains following the one-step dilution of whole blood. MS/MS spectra were recorded on a series of intact beta-chain human Hb variants. The resultant spectra were interpreted, and using the information gleaned from the fragmentation ...
