| Research Abstract |
The objects of this project are the preparation of the standardrized FABMS (Fast Atom Bombardment Mass Spectra) data acquisition format and the trial of the construction of FABMS detabase. The FAB mass spectrometry is used as a powerful tool for determining molecular formulae of non-volatile, high-molecular weight compounds, especially biochemical compounds. Though FABMS are very useful, its database is not completed yet for some difficulties. For executing this project, a scientist of the private corporation joined us and gave much more know-how's for measurements. The same samples of proteins, sugars and tetracyclins were measured by using several different type machines. From these FABMS data, the methods of data rearrangements and the standard conditions of measurements were examined. Therefore, the database contains not only spectral data an structural formula, but also detailed masuring conditions such as FAB targets, atomic species for bombardment, liquid matrices used, and etc. The conditions recorded in the database are quite useful for rhose who wish to measure similar kinds of compounds. For the knowledge database it has been tried that the structure informations of compounds from the fragment ion peaks are predicted by using the semiempirical MO calculations.
