A new method is presented to accurately determine the probability of having a deuterium or hydrogen atom on a specific amide position within a peptide after deuterium/hydrogen (D/H) exchange in solution. Amide hydrogen exchange has been proven to be a sensitive probe for studying protein structures

β¦ Synopsis
The use in Fourier-transform ion cyclotron resonance (FTICR) mass spectrometry of the collision-induced dissociation of proton-bound dimers, the kinetic method or Cooks's method, is tested. This method is compared with the proton-transfer equilibrium method. Good agreement between the two methods is observed. Advantages and limitations of the FTICR kinetic method are briefly discussed.

Trivalent and hexavalent chromium oxides have been examined by time-of-flight laser microprobe mass spectrometry and Fourier transform ion cyclotron resonance mass spectrometry (FTICRMS). The positive-ion spectra show a strong correlation with the valency of chromium in the oxide. Thus, the positive
