Positive and negative carbon cluster ions containing up to 27 carbon atoms have been produced by laser vaporization and detected via PT/ICR mass spectrometry. A periodic pattern of "magic numbers" is found in the positive clusters. The application of this technique to the study of ion-molecule react

The ions produced by "'Cf plasma desorption are detected by Fourier transform ion cyclotron resonance techniques. Results for CsI and N,N,N-trimethyl-p-aminophenolate iodide show the feasibility of the technique with high resolution (up to 11 000 at m / z 23) and good signal-to-noise ratio (up to 72
Silica clusters were produced by laser vaporizatian of three difierent silica compounds and the ionized species were analysed by using Fourier transform ion cyclotron resonance mass spectrometry. Using a wavelength of 248 nm, negativeion mass spectra of E2, Merck and Stober's silica showed different
## Abstract Posttranslational modifications such as glycosylation can play a fundamental role in signaling pathways that transform an ordinary cell into a malignant one. The development of a protocol to detect these changes in the preliminary stages of disease can lead to a sensitive and specific d
Raw oil shale, kerogen (demineralized shale) and carbonaceous residues from kerogen pyrolysis in the range 350-700°C (at 50°C intervals) were studied by laser ablation Fourier transform ion cyclotron resonance mass spectrometry using the fundamental frequency of Nd : YAG laser (1064 nm). Normally, p
## Abstract Quasimolecular peptide [M + H]^+^ ions are generated by matrix‐assisted (2,5‐dihydroxybenzoic acid/D‐fructose) laser desorption/ionization (frequency‐tripled Nd: YAG at 355 nm) from leucine enkephalin, bradykinin, the non‐apeptide Arg–Leu–Cys–Ile–Phe–Ser–Cys–Phe–Arg, angiotensin I, bovi
