✦ Synopsis


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 analogous cation-attachment oligosaccharide fragment ions for all three metal ions. A distinct and unusual fragmentation pattern is observed for the larger oligomers.

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

The time-of-flight effect in Fourier transform mass spectrometry (FTMS) with an external ion source was quantified. The time-of-flight profiles of ions of different masses were measured by stepping the time interval between the ionization pulse and the gating of the trapping voltage (T gate ). The o

Detection limits of poly(ethylene glycol) were examined in the mass range 2000-6000 Da. Using an aerospray sample deposition technique, highly uniform sample surfaces were produced. This method allows signal averaging of spectra from up to 400 shots on the same sample spot. It is found that, as the
