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...

Determination of synthetic ferric chelates used as fertilizers by liquid chromatography-electrospray/mass spectrometry in agricultural matrices.

A high-performance liquid chromatography-electrospray ionization/mass spectrometry (time of flight) method has been developed for the simultaneous determination of synthetic Fe(III)-chelates used as fertilizers. Analytes included the seven major Fe(III)-chelates used in agriculture, Fe(III)-EDTA, Fe(III)-DTPA, Fe(III)-HEDTA, Fe(III)-CDTA, Fe(III)-o,oEDDHA, Fe(III)-o,pEDDHA, and Fe(III)-EDDHMA, ...

Mass spectrometry studies of protein folding

Mass spectrometry has become a powerful method to study the structure and dynamics of proteins. Hydrogen/deuterium exchange in conjunction with mass spectrometry is now becoming more widely used to monitor conformational changes in proteins, and when combined with proteolytic digestion or gas-phase dissociation, it can provide spatial resolution of structural regions which participate in confor...

Metal chelates of glycine and glycine peptides.

Since the advancement by Smith et al. (l-4) of the theory that metal ions are chelated simultaneously to enzyme protein and substrate in various polypeptidases, the nature of metal binding to peptides and proteins has become an important as well as an interesting problem. The chelate structures proposed by Smith (3), and later somewhat revised (5, 6), indicate that the metal is bound, at least ...

Identification of aflatoxins by quadrupole mass spectrometry/mass spectrometry.

MS/MS daughter experiments were recorded for aflatoxins B1, B2, G1, G2, M1, M2, and aflatoxicol, using 3 ionization modes. Daughters were recorded from the molecular ion (M+) using electron impact ionization (EI). Daughters from the protonated molecules (MH+) were recorded in the positive ion mode and the daughters from the molecular anion (M-) were recorded in the negative ion mode using chemi...
