Figure 3. Lib. Search tab.
Placing the Mouse Pointer in one of these panes and clicking the Right Mouse button once will result in the display of a Right Mouse button menu. The last item on this menu is Properties. Selecting Properties will result in the display of a dialog box (Figure 4.) This dialog box has tabs at the top that are self-explanatory. This allows customization of the appearance of the display and control of what is displayed such as a structure on a spectrum, the 10 most intense peaks in the spectrum in the text display, etc. Colors of structures, mass spectral peaks and axes, and fonts used for alpha-numeric characters can also be set. Each pane can have its own customized set of attributes. This customized display can be saved using the File/Save Configuration command from the Main Menu Bar. Different saved configurations can be recalled by using the File/Restore Configuration command from the Main Menu Bar.
The first tab (lower left of the Program’s display), Lib.Search, is used with a search of a spectrum or structure against mass spectral libraries: a user library or the NIST 05 libraries (Figure 3). The spectrum and structure searches can be done against multiple libraries (maximum of 16), and the selected libraries can be different from those selected for the various searches found in the Other Search tab.
The second tab display, Other Search (Figure 5), is used to perform a Formula, CAS registry number, Molecular weight, Sequential, Any peaks, ID number, or NIST number search. The NIST number search can only be done on the NIST main library (mainlib) and its replicate library (replib). NIST numbers establish correspondence between spectra in different releases of the NIST/EPA/NIH MS Library. The ID number search can only be done on one library at a time. The other searches in this group can search multiple libraries (maximum of 16), and you can have different sets of libraries for each different type of search.
