Natural polymers, humic acid and lignins, were investigated by laser desorption (LD) Fourier transform mass spectrometry. In the vapor phase under LD conditions only positive ions of humic acid were observed up to m/z 700. Under the same conditions all the lignins investigated prefer to form negativ
Raw oil shale, kerogen (demineralized shale) and carbonaceous residues from kerogen pyrolysis in the range 350-700Β°C (at 50Β°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 Detailed structural information can be obtained without derivatization for a variety of naturally occurring pteridines by using laser desorption Fourier transform mass spectrometry. Laser desorption provides a soft ionization technique for these nonβvolatile compounds and generates char
Laser desorption mass spectra of malto-oligomers, including starch, have been obtained using Fourier transform mass spectrometry. Fragmentations of these oligomers have been examined after doping with metal salts to obtain cation-attachment ions. Doping starch with NaCl, KBr and Ag,O results in anal
